Physics for IGCSE & O level - Magnets And Currents (Section 5 - No. 15)
How can the induced e.m.f. be increased?
Increasing the speed of movement.
Increasing the strength of the magnetic field.
Increasing the length of the wire in the field.
Reducing the speed of movement.
Spiegazione
Increasing the relative speed, magnetic field strength or the wire length increases the induced e.m.f. Reducing speed decreases the e.m.f.
