(Option1)
The force of a current carrying conductor is given as:
F = BIL×sin∅
where,
B is magnetic flux density
I is current in conductor
L is length of the conductor
∅ is the angle between the magnetic field and current
Since ∅ is given as 90°,
F = BIL×sin90
(sin 90 = 1)
F = BIL
Hence, the force of magnitude between a current carrying conductor and magnetic field with 90° angle is equal to BIL.
