Questions and Answers List

Question	Answer
what is electromagnetic induction	if a wire is moved into a magnetic feild at right angles, voltage is induced. and if connected to a complete circuit a current it induced
ways to increase the size of the induced current	stronger magnet, stronger magnetic feild, move wire faster, wrap wire into a coil
what dictates the direction of the induced EMF?	it opposes the charge causing it, bar magnet approaches wire carrying a current which has been turned into a temporary magnet, this temporay magnet repels bar magnet approaching
