A simple DC motor consists of a single coil of 100 loops, rotating in a magnetic field with flux density B = 170 mT. The area of the coil is 3.50 × 10–4 m2. When the angle between the plane of the coil and the magnetic field increases from 15.0° to 45.0° the torque on the coil decreases by 5.39 × 10–3 N m. Calculate the current flowing through the coil.

A coil is free to rotate in a magnetic field with a flux density of 33 mT. The coil has 50 loops and an area of 25 cm2. A current of 0.75 amps flows through the coil. When the plane of the coil makes a certain angle with the magnetic field, the torque on the coil is 2.8 × 10–3 N m. If the coil rotates until this angle is doubled, what is the percentage change in torque?

A circular coil of 100 loops is positioned between the poles of an electromagnet so that the normal to the plane of the coil makes an angle of 25° with the direction of the field. The coil has a resistance of 3.0 Ω. When the magnet is switched off the magnetic flux density drops at a steady rate, from 0.50 T to zero in 0.10 seconds, causing an induced current of 1.2 A to flow in the coil. Calculate the...

A simple electric motor consists of a cylindrical armature with
a coil around it. A battery feeds current into the coil and this
produces a magnetic field around the it and so the armature became
an electromagnet. The magnetic field interacts with the armature
that generate a rotation. The commutator can change the direction
of the current every half-turn. This component can reverse the
north and the south poles of the armature and it create a rotation.
