An electromagnet is a magnet that only generates magnetic forces when electricity is running through it, basically a magnet that can be turned on and off. An electromagnetic field is the magnetic force generated when an electromagnet is used.
An Electromagnet is magnetic..... It can also be switched between positive and negative by the power source being turned around(battery)
Zero.
A magnet exerts magnetic force when 'at rest', or when it is not acted upon by any other force. An electromagnet exerts magnetic force only when energized by electricity, and is normally constructed from a ferrite core wrapped by an electric coil.
Really oversimplifying it: an electromagnet converts electric current to a magnetic field and an electric generator converts mechanical rotation to an electric voltage. An electromagnet has no moving parts while an electric generator is composed of a stationary part called the "stator" and a rotating part called the "rotor". An electric generator may contain either permanent magnets or electromagnets, depending on the type of generator.
magnetic circit has a magnet and electri circuit has electricity
Magnetic dipole is due to two poles of magnet. Electric dipole is due to +ve and -ve charges of electric charges.
An elecromagnet is the entire set of coils which produce a magnetic field when an electrical current is run through the wire. A solenoid is a single coil in the electromagnet.
The force is just one aspect of magnetism. For example, there is a magnetic field all around a magnet. Of course they are related, but "magnetism" is a wider term for the entire phenomenon - it may relate to the force, to the magnetic field, or to a few other things.
It is the joining of electricity and magnetic field, it is the study if the interaction between the two.
electromagnetism is the force an electromagnet is the object
A solenoid is a coiled wire with an electric current running through it, causing a magnetic field. An electromagnet is almost the same thing except it is much stronger than a solenoid (usually) and, unlike a solenoid, has a soft, iron core.
an electromagnet is a magnet which is activated by electricity and it ceases to be a magnet once the electric supply is stopped whereas a magnet is a natural magnet which does not need electricity and continues to be a magnet whether it is supplied by electricity or not.
