Electromagnetic Induction and Electromagnetic Waves

Flashcards covering key concepts of electromagnetic induction and electromagnetic waves.

Faraday's discovery led to __, which shows that a changing magnetic field can induce current.

electromagnetic induction

The phenomenon of __ refers to the current created in a nearby coil due to changing magnetic fields.

induced current

The formula for magnetic flux is __.

Φ = AB cos θ

According to Lenz's law, the direction of the induced current is such that it __ the change in magnetic flux.

opposes

When a magnetic field is decreasing, the induced magnetic field points __ the applied magnetic field, according to Lenz's Law.

in the same direction as

In an induction oven, __ causes heat transfer through the induced eddy current.

alternating magnetic field

The __ states that an emf is induced only when the magnetic flux through a loop changes with time.

Faraday's Law of Induction

The induced current in a circuit can be found using __ to determine the current direction.

the right-hand rule

Maxwell's theory indicates that a changing magnetic field induces an __.

electric field

Electromagnetic waves are described as a __ wave with electric field and magnetic field components that are perpendicular to each other.
