Where are the poles on a donut magnet?

This donut magnet has no poles. We should slightly correct the old answer. In an ideal donut-shaped (toroidal) magnet, the field outside the donut is zero. In that sense, it doesn’t behave like the horseshoe magnet, which can pick things up via the field outside the magnet.

How does the shape of a magnet affect its field?

If a magnet has a more pointed end, that end will be stronger than the rest of the magnet. This is because the shape affects the distribution of the magnetic energy in the space it occupies. This is due to the magnetic field concentrated between the poles, thus creating a stronger field.

What is a Doughnut magnet?

Donut Magnets These are very strong and compact magnets. The outer shell and center pin are both magnets. Components. The set is the Male and Female magnets.

Where magnets of different shapes are used and why?

For example, small horseshoes can collect paper clips while industrial-sized horseshoe magnets are used in construction and engineering to pick up large pieces of heavy metal. Horseshoe magnets are also used at the bottom of pendulums.

What is the connection between magnet size and strength?

Does the size of a magnet affect its strength? The short answer is yes, but only because the size of a magnet means that there are proportionally more domains that can align and produce a stronger magnetic field than a smaller piece of the same material.

In which direction do the magnetic field lines point near the South Pole of a magnet?

Thus, the magnetic field lines point away from the north pole of a magnet and toward its south pole. Figure 20.9 The black lines represent the magnetic field lines of a bar magnet. The field lines point in the direction that the north pole of a small compass would point, as shown at left.

How will you describe the magnetic field lines far from the magnet?

Magnetic field lines are defined to have the direction that a small compass points when placed at a location. (a) If small compasses are used to map the magnetic field around a bar magnet, they will point in the directions shown: away from the north pole of the magnet, toward the south pole of the magnet.

How does magnet move an object?

The object will be attracted to a magnet brought near it. For example, a magnet will move paper that is attached to the metal. Attach a magnet to an object. When another magnet is brought near it, the two magnets will either be attracted or repelled, and the object will move.

What do you think caused the magnet to move?

Magnetism is caused by the motion of electric charges. Each atom has electrons, particles that carry electric charges. Spinning like tops, the electrons circle the nucleus, or core, of an atom. Their movement generates an electric current and causes each electron to act like a microscopic magnet.

What is the north and South Pole of a magnet?

When a bar magnet is suspended in the Earth’s magnetic field orients itself in a north-south direction. The north-seeking pole of such magnet, or any similar pole, is called a north magnetic pole. The south-seeking pole, or any pole similar to it, is called a south magnetic pole.

What is the difference between like and unlike poles of magnets?

Unlike poles of different magnets tend to attract each other while the like poles are known to repel each other. The bar magnet is an easy device to visualize the magnetic poles. The two ends of a permanent magnet are called poles of a magnet. The force exerted by a magnet is depicted using curved lines with arrows.

What do the arrows on the magnetic field lines mean?

The arrows on the lines show the direction of a magnetic force i.e. from the North Pole to the South Pole of the magnet. Bar Magnet: Opposite poles attract while same poles repel each other. Breaking a magnet into two does not mean its North pole and the South Pole become isolated.

How do you test your understanding of magnetic poles?

Try to test your understanding of magnetic poles by answering this question. If you have two bar magnets with you, why is it that the like poles (north and north or south and south) of the magnet repel each other, whereas unlike poles attract each other? Understand different concepts in Physics by applying your knowledge.
