What is self-inductance?
💡 Hint: Think about what happens when you try to change the conditions in a coil.
True or False: Mutual inductance can only occur between two identical coils.
💡 Hint: Remember that coils only need to be close enough.

Calculate the induced emf in a coil with an inductance of 5 H if the current changes from 3 A to 0 A in 2 seconds.
💡 Hint: Make sure to convert your change in current correctly!
A transformer has a primary coil with 100 turns and a secondary coil with 50 turns. If the primary current changes at 2 A/s, what is the induced emf in the secondary coil, assuming mutual inductance M = 1.2 H?
💡 Hint: You only need to apply the formula for mutual inductance.
