Question

A current of 10A exists in a straight
wire. If it (wire) makes an angle of
30° with the magnetic field, the force
on 1 meter of the wire will be
(A) 7.5 newton(B)15 newton
(C)75 newton(D) 150 newton​

Answer 1

(A)

H=Bu-M

using of magnetic field formula

Answer 2

A current of 10A exists in a straight wire. If it (wire) makes an angle of 30° with the magnetic field, the force on 1 meter of the wire will be 7.5 newton. so, option (a) is correct.

• Power is the critical factor for the capacitor and resistance.
• The standard power unit is the watt; sometimes, it is measured in joules.
• Power is nothing but, it is the charge of the electric current.
• It is done between intervals of time.
• The power is the capacity of the work done.
• Energy applies to the fact of the momentum of energy.
• In that case, the well-known factor is that energy is not to be created nor to be destroyed.
• Energy is measured in the standard unit of a joule.
• The energy is to be indifferent they are chemical energy, electrical energy and light energy.
• The energy formula was invented by Albert Einstein.
• Energy is done by the form of motion.
• Energy falls under the scalar quantity.
• Force is the action done by external support.
• Force mainly occurs by the push or pull factor.
• In force, the object or particle should be in a condition of suspension or motion; it is calculated by how the object is moving or how it has been done.
• It also has both volume and movement.
• The standard unit is the newton.

Therefore, A current of 10A exists in a straight wire. If it (wire) makes an angle of 30° with the magnetic field, the force on 1 meter of the wire will be 7.5 newton.(a).
