Amagnet is pushed into the center of a wire loop and then stops. what is the current in the wire loop when the wire stops moving? explain.

-- If the ends of the wire loop are open (not connected to anything)
then there's never any current in it, no matter what you do with the
magnet.

-- If there's some kind of conductor between the ends of the wire
loop, then

-- While you're pushing the magnet, a current is flowing in the wire. 
The current creates a magnetic field around the wire, and some of
the energy you're using to push gets stored in the magnetic field.

-- When you stop pushing and the magnet stops moving, the energy
stored in the magnetic field keeps the current flowing in the wire for
a short time, and then everything stops.

This all happens so fast, and lasts for such a short time, that you'd
never notice it unless you were set up with special equipment to
measure it.

Ithink the answer would be 1,350!

Wind or electric energy force force of friction
