ppefmh	Ed	Garstin	2/2	When we induce a current in a coil of wire, this causes the coil to develop its own magnetic field.			When we push the bar magnet into the coil a current is induced in the coil. The induced current causes the coil to develop a magnetic field which repels the bar magnet, making it harder for the magnet to move in. When we push the bar magnet into the coil a current is induced in the coil. The induced current causes the coil to develop a magnetic field which attracts the bar magnet, making it easier for the magnet to move in.	gdf	100%
