What are the arrangement of moving magnets and wire coil called?
electromagnet
What does a electromagnet have that a bar magnet does not have?
The bar magnet and the electromagnet act identical. The difference being a electromagnet is a coil of wire that has a power source connect to both ends, this energizes the coil with an electromagnetic field.
Strong temporary magnet formed when a current is passed through a coil of wire?
A magnetic field.
What has a wire-wrapped core?
A coil of wire or a coil in the shape of a cylinder is a typical shape for an electromagnet (or a solenoid). The strength of the magnetic field of an electromagnet can be increased significantly if the coil is wrapped around an iron core. This configuration may be called an inductor when used as an element of an electrical circuit.
What must pass through a coil in order to make an electromagnet?
An electrical current will cause an electromagnet to energise.
How does a coil act?
a coil acts as an electromagnet.
Could you make an electromagnet by wrapping a coil around a wooden core?
It can, it just wouldn't be permiable.
What is the relationship between the stength of an electromagnet and the number of turns in the coil?
As the number of turns in the coil increases, the strength of the electromagnet increases.

The bar magnet and the electromagnet act identical. The difference being a electromagnet is a coil of wire that has a power source connect to both ends, this energizes the coil with an electromagnetic field.
How can you strengthen an electromagnet?
make an electromagnet stronger by doing these things: * wrapping the coil around an iron core * adding more turns to the coil * increasing the current flowing through the coil.
Strong temporary magnet formed when a current is passed through a coil of wire?
A magnetic field.
What type of magnet is created when electric current flows through a coil wire?
electromagnet
Is the core of an electromagnet a piece of steel in the center of the coil?
no
A coil of wire with an electric current in it is called?
electromagnet
Two ways to increase the strength of an electromagnet?
-- Increase the current (amperes) flowing through the coil of wire that surrounds the electromagnet. -- Increase the number of 'turns' of wire in the coil.
