Chapter 5 - Magnetism and Electromagnetic Induction

X

An indicates a magnetic field going into the page (think of the back of an arrow)

Lenzs Law

__ states that the direction of the induced current opposes any change in flux.

Magnetic field lines

are loops that point away from the North and toward the South.

Solenoids

hooked up to a battery create a dipole magnetic field like a bar magnet.

Magnetic

and electric fields extend into infinity and get weaker with increased distance.

Diamagnetic materials

Magnets weakly repel .

Ferromagnetic materials

Magnets strongly attract .

Mass Spectrometer

A is a device used to determine the charge to mass of a particle by arcing them in a magnetic field and finding the radius of its path

Magnetic Flux

____ is a measure of the magnetic field passing through an area
