Magnetism and Electromagnetic Induction

There is no change in induced emf.

The induced emf decreases.

The direction of induced emf reverses.

The induced emf increases.

Tesla (T)

Ampere-turns (At)

Weber (Wb)

Henry (H)

It decreases both the number of emitted photoelectrons and their kinetic energy.

It increases both number and kinetic energy of emitted photoelectrons equally.

It increases the number of emitted photoelectrons but not their kinetic energy.

It has no effect on either number or kinetic energy of emitted photoelectrons.

It halves due to increased resistance with more wire length involved after doubling turns.

It doubles since both primary and secondary windings have doubled their turns.

It quadruples as increasing both coils’ winding results in exponential growth in induced voltage.

It remains unchanged because it depends on turns ratio rather than total number of turns.

A solenoid with high inductance

Another capacitor with equal capacitance

Removing any additional components from circuitry

An identical resistor

A shadow of the slit is formed by electron blockage.

The electrons spread out uniformly across the screen.

Each electron forms a single point directly opposite its respective slit.

They produce an interference pattern similar to waves.

Secondary voltage varies unpredictably.

Secondary voltage decreases.

Secondary voltage increases.

No effect; secondary voltage depends on turns ratio and primary voltage only.

$B = \mu_0 (NI)$

$\varepsilon = -N \frac{\Delta \Phi}{\Delta t}$

$F = q(vB)\sin(\theta)$

$\varepsilon = N \frac{\Delta B}{\Delta t} A$

Loop material must transition between ferromagnetic and nonmagnetic states while maintaining initial spatial positioning relative to fields.

Static charge distribution on surface bounding loop should be varied without influencing magnetism directly.

Relative geometric orientation between loop and magnetic field lines must be changed.

Magnetic permeability inside area confined by loop needs alteration while keeping geometry fixed.

Wind more turns tightly on each layer of coil being used in experimentation.

Shorten all connecting wires while maintaining their material and thickness.

Increase wire thickness to double its original diameter.

Replace existing wires with ones having lower electrical resistance.
