Electromagnetic Induction Concepts

What components are used in the setup to study electromagnetic induction?

• A light bulb, a wire, and a power source

• A capacitor, a diode, and a transformer

• A battery, a resistor, and a switch

• A bar magnet, a coil, and a galvanometer

What happens to the galvanometer when the magnet is moved near the coil?

• It shows a constant deflection

• It shows a momentary deflection

• It does not deflect at all

• It deflects permanently

When does the galvanometer stop deflecting?

• When the galvanometer is disconnected

• When the coil is removed

• When the magnet is at rest

• When the magnet is in motion

What causes the changing magnetic field in the setup?

• The motion of the coil

• The motion of the magnet

• The rotation of the galvanometer

• The presence of a battery

What is the phenomenon called when a changing magnetic field induces current in a conductor?

• Electromagnetic interference

• Electromagnetic resonance

• Electromagnetic radiation

• Electromagnetic induction
