Relationship of magnetism and electricity Flashcards
one of the phenomena by which materials exert attractive or repulsive forces on other materials.
magnetism
this produces magnetic forces and have magnetic field lines
magnets
what are the two ends of the magnet?
north and south poles
he is a Danish physicist and chemist, and
a professor
hans christian oersted
The magnetic field of a coil is identical to the field of a disk-shaped permanent magnet. (true or false)
true
this is the most common form of electromagnetic device
solenoid
a magnetic field that is produced by a current of electricity
electromagnetism
an electromagnet that interacts with a permanent magnet. The stronger the electric current passing through the electromagnet, the more is interacts with the permanent magnet.
galvanometer
a process where a conductor is placed in a changing magnetic field (or a conductor moving through a stationary magnetic
field), causing the production of a voltage across the conductor. this process causes an electrical current.
electromagnetic induction
he discovered the electromagnetic induction
michael faraday (1831)
Current is only produced if the magnet is moving because a changing magnetic field is what creates current. (true or false)
true
If the magnetic field does not change, such as when the magnet is stationary, the current is zero.(true or false)
true
