A permanent magnet is inserted into the short-circuited coil: once quickly, and the second time slowly. Compare the induction current values.
Electromagnetic induction
1) Faraday’s law of electromagnetic induction.
2) Ohm’s law.
2) Let us analyze and understand that dФ / dt is the rate of change of the magnetic flux.
q 1> q 2.
Q = I * d t (1).
I = E / R = dF / R * dt (2).
Substitute 2 in 1
q = d Ф / R.
With fast movement of the magnet d Ф1> d Ф2.
