Which will be attracted to (or repelled by) a magnet ?
check all that apply.
a.) an iron horseshoe
b.) an aluminum rod
c.) a copper wire carrying current
d.) a positively charged glass rod
e.) a copper wire not carrying any current
f.) another magnet

A.) An Iron horseshoe

C.) A copper wire carrying current

F.) Another magnet

Explanation:

As we know that two magnets and two different magnetic materials will attract or repel each other

This is due to interaction of two materials due to which their magnetic field interacts and apply force on each other

Here we know that

magnetic field due to current carrying wire is given as

so here the magnetic fields will interact when a current carrying wire is placed near the magnet, or another magnet is placed near the magnet or any magnetic material like iron horse shoe is near it

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.
