what is electromagnet induction and what is it also known as
when a voltage is induced in a coil when it moves through the magnets magnetic field
(there is not current flowing through the coil yet)
when is a voltage induced
a coil moving through a magnetic field
magnetic field strength changes
area of coil changes
what factors increase the induced voltage
stronger magnetic fields
more number of coils
larger coil area
what are the two ways that make a wire induce a voltage
rotating a magnet in the coil
rotating a coil inside the magnetic field
how does rotating a magnet in the coil induce a voltage
when the magnet rotates it makes the direction of the magnetic field lines and the strength change. This makes the coil also experience it making it induce a voltage.
how does rotating a coil induce a voltage
when the coils cut through thee magnetic field lines inducing a voltage
