Induced Potential (ht Only) (GCSE Physics)

A conductor moving parallel to magnetic field lines produces

When a straight wire moves up through a magnetic field, a current is induced. Which energy conversion occurs?

A bar magnet is pushed toward a stationary loop. The induced emf in the loop will be greatest when

A single-turn conducting loop in a changing magnetic field has an induced emf of 0.50 V. If the same changing field acts on a coil of 500 identical turns, the induced emf in that coil will be

When the magnetic flux through a coil is constant but the coil is deformed so its area decreases while still perpendicular to the field, the induced emf is

A straight wire of length L moves with velocity v through a magnetic field B so that v, L and B are mutually perpendicular. The induced emf equals

Which quantity is directly proportional to the induced emf in a coil when the coil has N turns?

Which effect explains why a current in a wire inside a magnetic field can cause a force on the wire (motor action)?

Which practical application relies on induced emf when a conductor cuts magnetic field lines and produces a usable voltage for charging?

A loop cuts magnetic field lines so the magnetic flux through it decreases. Which is true about the induced current?

A conductor of length 0.50 m moves at 4.0 m/s perpendicular to a uniform magnetic field of 0.20 T. What is the magnitude of the induced emf across the ends of the conductor?
