Pooja Parekh Induction Lab PHY 134 Section 2 Main Analysis Induction 1. Changing the magnetic field on the coil affects the direction of current passing  through it. Only when there is changing field does it cause a current. When point  the North Pole into the magnet when a positive change in the current occurs.  When the bar magnet is taken out, a negative change in the current occurs. For the  South Pole, a negative change in the current occurs when the bar magnet is put  inside the coil. A positive change in the current occurs when the bar magnet is  taken outside the coil. 2.     The side opposite to the side that goes into the larger coil is the north. When the current is turned on and off in the case of a smaller coil inside the larger coil, a  positive change in the current occurs with a magnitude of .15 units of current. When the direction
