What would happen if a copper rod is brought towards a bar magnet suspended from a thread?

The field of the rod would interact with the field of the magnet to produce repulsive forces between rod and magnet, so the magnet will tend to swing away from the rod.

What happens when a magnet is placed near a copper wire?

Magnetism and electricity are closely related. When a magnet moves near copper (or other metals) it sets up electrical eddy currents. The eddy currents will repel the magnet as it falls down the copper tube. This repulsion pushes against the magnet and slows it down.

What force is acting on the suspended bar magnet?

Answer: Explanation: When a bar magnet is suspended freely in a uniform magnetic field, The magnet experiences only couple and undergoes only rotatory motion experience any force.

How can you tell if a bar is magnetized?

How can you identify which one is a magnet? Solution: You can hang the iron rods on a string and watch which one turns to the north (or hang just one rod). Gardner gives one more solution: take one rod and touch with its end the middle of the second rod. If they get closer, then you have a magnet in your hand.

In which direction the copper ring will move with respect to magnet?

When we move the copper ring towards the north pole of the bar magnet, the current gets induced in the copper ring in the anticlockwise direction. The induced current in the loop produces a magnetic dipole and the orientation of the magnetic dipole is such that it opposes the movement of the copper ring.

What happens if a magnet is broken into two pieces?

When we break a bar magnet into two pieces, the bar magnet does not lose its properties. The new pieces now behave as individual magnets, each having a north and a south pole. The north and the south poles of the two magnets have their north and south poles at the same side as that of the original magnet.

What would you observe when a bar magnet is allowed to fall within hollow copper tube?

Results. When you drop your magnet through a copper tube, it slows down. The magnet will also slide down the cookie sheet slowly, and nudge the metal washer in the direction the magnet is spinning. The voltage will spike when the magnet is moving next to the metal, but not when the magnet is sitting still.

What would you observe when a bar magnet is allowed to fall within hollow copper tube suggest reasons for the same?

If bar magnet is falling vertically through the hollow region of long vertical copper tube then the magnetic flux linked with the copper tube (due to ‘non-uniform’ magnetic field of magnet) changes and eddy currents are generated in the body of the tube by Lenz’s law the eddy currents opposes the falling of the magnet …

What will happen if we suspend a magnet freely?

If we suspend a magnet freely, it will settle in North-South direction. All magnets have two poles north (N) and south (S) poles are marked on the magnets. The Earth itself behaves as a magnet which causes a freely suspended magnet to point in a particular direction – North and South.

What happens to the suspended magnet?

If we suspend a magnet by a string from its center so that it is free to turn, it will turn until there axis lines up with its poles, lying along the earth’s magnetic north and south poles. The pole which points north is called the north pole and the other is called the south pole.

How will you differentiate between an iron rod and a magnetic rod?

So when we are given two identical looking magnets and iron rods, one way to distinguish between them is by the magnetism property of a magnet. Iron rods will stop in different ways, but the magnetic rod will be aligned only in one direction. In this way also we can find the real magnetic rod among them.

What happens when you put two bar magnets together?

If you bring two bar magnets together, there are two things that can happen, attraction and repulsion: 1 if you bring a north pole and a south pole together, they attract and the magnets stick together 2 if you bring two north poles together, or two south poles together, they repel and the magnets push each other away More

What happens when you put magnets on a copper plate?

If you drop strong magnets onto a plate of copper, something remarkable happens: the magnets will slow down before hitting the surface, appearing to levitate slightly, like the copper is another magnetic force pushing them away. There’s a fascinating explanation for this, as told in this video by NightHawkInLight.

How many magnetic poles does a bar magnet have?

A bar magnet has two magnetic poles: north pole (or north-seeking pole) south pole (or south-seeking pole) The north pole is normally shown as N and the south pole as S

What do magnets pull on metal?

Magnetic fields A magnet will pull on some metals like iron. If we bring the north pole of one bar magnet up to the south pole of another one, they will attract each other. A magnet does not have to be touching another magnet to pull it or push it.
