Answer 1

I believe it’s A C F

Answer 2

A.) An Iron horseshoe

C.) A copper wire carrying current

F.) Another magnet

Step-by-step 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

`B = (mu_o i)/(2\pi r)`

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
