Increasing the number of turns increases the inductance.

A changing magnetic field induces an EMF (voltage) and can cause current to flow in the conductor.

An induced current is generated in the loop, creating a magnetic field that opposes the increase in flux.

Increasing the resistance decreases the time constant, causing the current to reach its maximum value faster.

A magnetic field is created by both electric currents and changing electric fields.

The process of generating electricity using a changing magnetic field.

The amount of magnetic field passing through a given area, calculated as $\Phi_B = B cdot A cdot cos(\theta)$.

A measure of how much a coil resists changes in current, measured in henries (H).

A measure of how quickly the current in an LR circuit reaches its steady-state value, calculated as $\tau = \frac{L}{R}$.

A changing magnetic field induces an electromotive force (EMF), with the magnitude of the EMF proportional to the rate of change of magnetic flux: $\mathcal{E} = -N \frac{d\Phi_B}{dt}$.

The direction of the induced current opposes the change in magnetic flux that caused it.

Faraday's Law: Quantifies the magnitude of induced EMF. | Lenz's Law: Determines the direction of the induced current.

Immediately after: Current starts at zero and gradually increases due to the inductor's opposition. | After a long time: Current reaches its maximum value, limited only by the resistance.
