Electromagnetic Induction Simulation
Example 6.5: Faraday's Law Demonstrations
Part (a): Stationary Loop in Magnetic Field
Can we generate current in a stationary loop between strong magnets?
Solution: No. However strong the magnet may be, current can be induced only by changing the magnetic flux through the loop.
ε = -dΦB/dt (Faraday's Law)
Part (b): Loop in Capacitor's Electric Field
Is current induced when moving through a capacitor's electric field?
Solution: No current is induced in either case. Current cannot be induced by changing the electric flux.
Part (c): Rectangular vs Circular Loop Exiting Field
Which loop maintains constant induced emf when exiting a uniform field?
Solution: The induced emf is expected to be constant only in the case of the rectangular loop. In the circular loop, the rate of change of area during exit isn't constant.
ε = -B(dA/dt) (For constant B and v)
Part (d): Capacitor Polarity Prediction
Predict the polarity of the capacitor in the given situation.
Solution: The polarity of plate 'A' will be positive with respect to plate 'B' in the capacitor.
