The main contact controls the load current to the motor, whereas the auxiliary contact is part of the control circuit -usually connected in parallel with the 'on' pushbutton switch to maintain the control circuit in the energised state, once the on pushbutton has been pressed.
The electric power is measured the same as in any other electric circuit, in watts. You calculate this by multiplying the current (in amps) by the potential difference (in volts) across the circuit. So: P = I V If you meant how do we measure the strength of the magnetic field generated, there are two different vector fields that may be called "magnetic field". These are the H-field and the B-field. The H-field may also be called the "magnetic field intensity", the "magnetic field strength", the "auxiliary magnetic field" or the "magnetising field". It is measured in amps per metre. The B-field may also be called the "magnetic flux density", the "magnetic induction", or the "magnetic field". It is measured in teslas.
If you meant which symbol carbon is, it is C.

The phrase trans ocean is meant to mean across the ocean. Trans ocean is meant to be the same as transocean, which is not a word but a shorter version of transoceanic, to which it is meant to have a similar meaning.
So the forces acting on these charges have to be compared. Is it so? The famous formula meant to know about the force acting on a moving charged particle entering into a magnetic field is given as F = B q v sin@ Here @ is the angle inclined by the moving particle with the magnetic field. In the first case @ = 90 deg. As sin90 = 1 the force is Bqv. In second case @ = 30 deg. As sin 30 = 1/2 the force is 1/2 Bqv. Hence the force on the latter will be half of that on the earlier one.

All materials are magnetized when placed in the magnetic field . The material magnetized by the effect of a magnetic field is called magnetic permeability.
give Langevins theory of paramagnetism?
Diamagnetism is weak repulsion by a magnetic field.

conection between two or more magnetic circuits magnetically with out any electrical connection .i.e.'flux linkages are there inbetween the magnetic circuits.
Lines of force go from a North pole of a magnet to the South pole external to a magnet, and through the magnet itself. This path is the magnetic circuit. It may be diverted and distorted by magnetic materials nearby.

when a magnetic substance in placed i two uniform magnetic field (b) and (h) which are mutually perpendicular and coplanar to each other. then the magnetic field intensity of magnetic field of b which making angle θ with h is tanθtimes of h.mathamatically B=tanθxH.

A radial magnetic field ensures that the plane of the coil (rotating within the magnetic field, in say a DC motor) is always flat within the external magnetic field ensuring maximum torque in (nearly) all positions. Hope this helps!
There is no such thing as a Philanthropoligist. Perhaps you meant "philanthropist"?
