A nail touches a magnet will a)generate an electric current b)melt c)demagnetize the magnet d)become polarized
Yes A nail is touch into bar magnet it becomes polarized
Because the number of magnetic field lines are surrounding
To the nail
So the molecules in the nail is attracted by the bar magnet
And the nail is get magnetic nature but opposite nature of the bar magnet
A nail touches a magnet will a)generate an electric current b)melt c)demagnetize the magnet d)become polarized

If a bar magnet is falling through a loop of wire, the induced current in the loop of wire sets up a field which exerts a force on the magnet. This force between the magnet and the loop will be repulsive when: A. the magnet enters the loop B. the magnet is halfway through C. the magnet is leaving the loop D. never Please provide an explanation!
