  • the magnetic field is strongest at point

    See the answer. The field is strongest on the poles of the magnet (the ends of the magnet). left. Magnetic field lines can never cross, meaning that the field is unique at any point in space. The magnetic field is strongest at the poles, where the field lines are most concentrated. What is the magnetic field strength at point a, b and c and what are the directions at each point? The effects of magnetic fields are commonly seen in permanent magnets, which pull on ferromagnetic materials such as iron, and attract or repel other magnets. It is exactly proportional to the number of lines per unit area perpendicular to the lines (called the areal density). A solenoid is a combination of closely wound loops of wire in the form of helix, and each loop of wire has its own magnetic field (magnetic moment or magnetic dipole moment). Question: The diagram below represents a 0.5-kilogram bar magnet and a 0.7-kilogram bar magnet with a distance of 0.2 meter between their centers. (a) The field is strongest at points B and D . 1. The spin of these electrons can be aligned, resulting in very strong magnetic fields, and therefore, these elements are used in compact high-strength magnets where their higher price is not a concern. The last property is related to the fact that the north and south poles cannot be separated. Copyright © 2020 Multiply Media, LLC. Whenever current travels through a conductor, a magnetic field is generated, a fact famously stumbled upon by Hans Christian Ørsted around 1820. The inclination of the Earth's field is 90° (downwards) at the North Magnetic Pole and -90° (upwards) at the South Magnetic Pole. Surveyors will tell you that overhead electric power lines create magnetic fields that interfere with their compass readings. The force the dipole experiences is proportional to the strength of the dipole and proportional to the rate at which the magnetic field changes. For these diagrams, I used a … It's called the solar minimum. Magnetic Fields DRAFT. Weak magnetic field If the magnetic field lines are far away from each other in a particular region ,then the strength of the magnetic field in that region is very small or … Whenever current travels through a conductor, a magnetic field is generated. 4 Magnetic Fields Around Magnets Figures 2 and 3. When the field lines are close together, the magnetic field is strong. Did you know that the magnetic field of a magnet is not uniform? Figure 20.9 The black lines represent the magnetic field lines of a bar magnet. What is the strongest point in a magnetic field. Two bar magnets. Farther away, where the magnetic field is weak, they fan out, becoming less dense. All Rights Reserved. Thus, the magnetic field lines point away from the north pole of a magnet and toward its south pole. Solenoids have many practical implications and they are mainly used to create magnetic fields or as electromagnets. Figure 7: Magnetic force between current loops. Edit. The force is weaker in the middle of the magnet and halfway between the pole and the center. She has taught science courses at the high school, college, and graduate levels. What this indicates is that the magnetic field varies strongly over a short distance compared to the variation closer to the middle of the magnet. Therefore, of the four points, the magnetic field is weakest at point D. What are the release dates for The Wonder Pets - 2006 Save the Ladybug? The field lines point in the direction that the north pole of a small compass would point, as shown at left. a year ago. The local definition is the point where the magnetic field is vertical. Depending on the shape of the conductor, the contour of the magnetic field will vary. Save. (b) The field is strongest at points A and C . Venus has no measurable magnetic field, most likely because the planet rotates extremely slowly. The magnetic poles are also where the magnetic fields are the strongest. The magnetic field pattern when two magnets are used is shown in this diagram. 25, 2018 — Around four billion years ago, the moon had a magnetic field that was about as strong as Earth's magnetic field is today. Expert Answer 100% (61 ratings) Previous … It is exactly proportional to the number of lines per unit area perpendicular to … The lowest magnetic field line density indicates the smallest magnetic field strength. The field is strongest on the poles of the magnet (the ends of the magnet). The magnetic field direction is the same direction a compass needle points, which is tangent to the magnetic field line at any given point. Answer: (B) has the greatest magnetic field strength because it is located at the highest density of magnetic field lines. Because the magnetic field changes so dramatically, a dipole feels more force. This can be determined by measuring the inclination. Magnetic fields may be represented mathematically by quantities called vectors that have direction as well as magnitude. A small compass will point in the direction of the field line. What are some samples of opening remarks for a Christmas party? The ends of a magnet where the forces are the strongest are called magnetic. How long will the footprints on the moon last? The Geomagnetic South Pole is estimated to be located at 79.74˚S and 108.22˚E. The field is strongest on the poles of the magnet (the ends of the magnet). The magnetic field is strongest in the area closest to the wire, and its direction depends upon the direction of the current that produces the field, as illustrated in this interactive animation. The diagram below shows the magnetic field that results when a piece of iron is placed between unlike magnetic poles. When did organ music become associated with baseball? Physics for Scientists and Enginee... 9th Edition. Well, that's the permeability of the material that the wire's in. The force is weaker in the middle of the magnet and halfway between the pole and the center. The direction of the magnetic field is tangent to the field line at any point in space. Because the Sun's magnetic field controls its activity - sunspots (temporary regions of strong magnetic fields), solar flares, and coronal mass ejections (produced by magnetic field lines snapping and reconnecting) - this stage of the cycle manifests as a period of very minimal activity. For a point near the centre of the disk, the magnetic field is very small because the contributions of the nearest magnetic dipoles is parcially canceled by the rest of the dipoles because its contribution is antiparallel. How many candles are on a Hanukkah menorah? At which point is the magnetic field strength greatest? The close continuous curves in a magnetic field are called magnetic lines of force. Iron filings make a pattern tracing field lines because each bit of iron is itself a tiny dipole (the separation between magnetic fields). dcrust. The field lines are closely packed at either pole of the magnet, widening as they get farther from the pole and connecting to the opposite pole of the magnet. Those filings even farther away, outside the magnetic force, will point north in response to the earth’s magnetic field. poles. Buy Find arrow_forward. Dr. Helmenstine holds a Ph.D. in biomedical sciences and is a science writer, educator, and consultant. The strength of the B-field is inversely proportional to the distance between field lines. (1) A (3) C (2) B (4) D 3. The magnetic field lines emerge from the north pole and enter the south pole. At the poles of a magnet, for example, where the magnetic field is strong, the field lines are crowded together, or more dense. Expert Answer 100% (5 ratings) Previous question Next question Transcribed Image Text from this Question. At which point is the magnetic field strength greatest?
