Saad Ghazipura Induction Lab PHY 134  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. 3.

What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

Dana University of Pennsylvania ‘17, Course Hero Intern

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
