Q- A conductor of length (L) carrying current of
magnitude (i) is placed in a magnetic field of strength (B),
experiences a magnetic force, F. If the conductor is oriented in a
such a way that the angle between the magnetic field and the wire
is (ɸ).
A) State the relationship between ɸ, i, F, B and L
B) If F=2 N, i=20A, B=150mT, and the length of the
conductor is 135cm, What is the angle between the conductor and the
magnetic field?
C) If the same conductor under the same conditions is
held perpendicular to the magnetic field, what would be the new
magnetic force, F acting on it?

The size of the magnetic force on a straight wire of length
L carrying current I in a uniform magnetic field
with strength B is
F=ILBsin(?).
Here ? is the angle between the direction of the
current (along the wire) and the direction of the magnetic field.
Hence Bsin(?) refers to the component of the
magnetic field that is perpendicular to the wire, B?. Thus
this equation can also be written as
F=ILB?.
