Electromagnetic Induction 4.5

Question 1

define lenzes law

Answer 1

direction of the inward EMF if such that it will try to oppose the charge in flux that its creating.

Question 2

What is halls probe?

Answer 2

electrons flow opposite of current and due to FLHR electrons motion is up.

Question 3

define eddy currents.

Answer 3

currents that take closed loops in conducting material in bulk.

Question 4

define electromagnetic damping?

Answer 4

This is the slowing of motion due to forces experience by induced currents.

Question 5

define self-induction

Answer 5

induction of EMF in a coil because of the changing current in the coil.
