Which are not considered electro magnetic devices

(select all that apply)

What happens when a conductor moves perpendicular to a magnetic field?

What happens when a conductor moves parallell to a magnetic field?

direction of movement determines polarity of voltage induced

changing the direction of movement doesn't change the direction of current flow

A generator changes ____ energy into ____ energy

An electric motor changes ____ energy into ____ energy

A ____ doesn't move and holds parts togather

the ____ rotates and has voltage induced

____ connects armature to the output

____ converts AC voltage induced in the armature into DC voltage

In series

in parallell

metals that are easily magnetized. Iron, nickel, cobalt, and manganese

metals that can be magnetized, but not as easily as ferromagnetic materials. Platinum, titanium, and chromium

are either metal or nonmetal materials that cannot be magnetized. The magnetic lines of force go around them instead of through them. Copper, brass, and antimony

which of the following can demagnetize a magnet

energy is required to maintain a permanent magnetic field

electrostatic and magnetic fields exist at right angles to each other and they combine to form a(n) electromagnetic field.

a customer wants you to install an attic vent fan powered by 120V, 3 hp motor and wants you to tell him approximately how much it will cost to operate per day. Power in his area costs 10 cents per kilowatt hour
