Magnetic Evasion

Electrons moving in a magnetic field experiences a magnetic force F=Bqvsinθ.

In this comic, the electrons are learning how to avoid magnetic deflection, either by being stationary, or by moving parallel to the magnetic field. Haha.

Electron Rush

Motional EMF (ε=BLv) occurs when a conductor “cuts the magnetic flux”.

In this comic, the wire in the middle is the only one moving perpendicularly to the magnetic field, resulting in induced EMF across its two ends. Haha.

Faraday’s mother-in-Law

Faraday’s Law (ε=-dΦ/dt) implies that a constant magnetic flux results in no induced EMF. EMF is induced only when there is a CHANGE in magnetic flux linkage.

In this comic, the elderly lady is not bothered by extreme temperatures. She is only bothered by CHANGEs in temperature. Haha.
