A rectangular coil of wire can rotate in a magnetic field. The ends of the coil are soldered to the two halves of a split ring. Two carbon brushes are made to press lightly against the split ring and when these are connected in circuit with a battery and rheostat, the coil rotates. This is a description of
a suspended- coil vanometer
a moving-cell ammeter
a d.c generator
an electric motor
an induction coil,

The answer is wrong
An electric motor is a device which converts electrical energy to mechanical energy
In the question above ,a battery is the source of electrical energy
A DC generator is used to convert mechanical energy to direct current,in this are no battery is connected to the split rings via the carbon brushes are
the answer should be an electrical motor mainly because a baterry was connected and the total setup caused rotation of coil.
for a motor current is inputed and motion is produced
it cant be a genrator because of the battery connected ,the genetator supplies currnt it doesnt need a battery to supply it with it
Please my school the answer is an electric motor because of the connection of the battery
The answer is D.
A DC generator does not have a battery.
An electric motor has a battery
