I am having trouble understanding right hand rule for Lenz's Law.
I need to know how to use the right hand rule with lenz'z law to find the dircection of induced current.
What if a current is flowing clockwise, with mag. field going into page, is the magnetic field strength increasing or decreasing?
I understand that if I point my thumb in the direction of current, my "curled" fingers will show the direction of the magnetic field created by wire.
I have not found any good explanations into this rule....Following are example problems:
A circular wire loop 40 cm in diameter has 100 resistance and lies in a horizontal plane. A uniform magnetic field points vertically downward, and in 28 ms it increases linearly from 4.0 mT to 53 mT. Which way does this current flow?
The magnetic field perpendicular to a circular loop of wire 16 cm in diameter is changed from +0.52 T to -0.45 T in 204 ms, where + means the field points away from an observer and - toward the observer. In what direction does the induced current flow?
