If a bar of copper is brought near a magnet, copper bar will be?

Question

A. attracted by the magnet.
B. unaffected by the magnet.
C. repelled by the magnet.
D. made into an induced magnet.

Answer 1

B. unaffected by the magnet

this is the correct answer, because :

For A. to happen it should have material like iron in it to get attracted.

For C. to happen it should be a magnet itself and Copper can't be a magnet (see why D is wrong)

For D. It should be a material where as small magentic domains within the material can align themselves to become a magnet. Copper does not have this property. D can happen only for magentic materials (those that can be made into induced magent) but Copper is not such a material.

So A,C,D are wrong.

Hence the correct answer is B (Copper remaiins unaffected by magnet is true).

Answer 2

B - it heavily isn't affected. be conscious: truly, all issues impact and are stricken by technique of magnetic fields. inspite of the undeniable fact that, many products, copper and aluminum blanketed, do no longer exhibit something it really is seen to the interest. Copper also makes an awesome, even inspite of the undeniable fact that extreme priced, shunt for magnets.

Answer 3

if the bar is stable then B if you spin the bar at a high rate of speed it creates magnetic field so then A or C trains in japan use compounds of aluminum and copper to produce magnetic fields
