5 Questions
According to Lenz's law, what is the direction of the induced magnetic field in relation to the change in area?
Opposes the change in area
What type of current is used to continuously change the magnetic field produced by a solenoid?
Alternating current (AC)
How can wireless induction occur between two solenoids without them physically touching?
By having a constantly changing external magnetic field from one solenoid induce current in the other solenoid
What happens to the induced current when the area of a loop of wire changes?
Induced current is generated
How can the magnitude of the external magnetic field produced by a solenoid be altered?
By varying the supplied current
Test your understanding of Lenz’s law and the determination of the direction of induced magnetic fields and current when there is a change in flux. Learn how to use the change in area to determine the directions of induced fields due to flux changes, while the external magnetic field remains constant.
