The region where the iron filings aligned themselves is the magnet’s

(a)  

invented the first practical source of steady current.

(a)  

The pattern formed by iron filings is called the

(a)  

It is the number of group of lines passing through a unit area

(a)  

States that the force of attraction or repulsion between two magnetic poles directly proportional to the strength and inversely proportional to the square of the distance between them.

(a)  

It is the study of the relationship between electricity and magnetism.

(a)  

The relationship between electricity and magnetism were accidentally discovered by a Danish chemist and physicist

(a)  

In (a)   , Oersted discovered that a magnetic needle is deflected at right angles when brought near a wire carrying electric current.

It is a magnet produced by a current flowing through a coil of wire.

(a)  

-        It is a of producing electric current by an action of magnetic field.

(a)  

Device can be used to determine the polarity of an unmarked magnet

(a)  

·        states that the emf induced in a loop of wire is proportional to the rate of change of magnetic flux through the coil.

(a)  

·        States that the direction of an induced current is such that it sets up its own magnetic field which opposes whatever action is responsible for the production of the current.

(a)  

It is a device that creates an electric current by rotating its coil through a magnetic field.
