A straight wire 0.10 m long carrying a current of 2.0 A is at right angles to a magnetic field.
The force on the wire is 0.04 N. What is the strength of the magnetic field?
The force on the wire is 0.04 N. What is the strength of the magnetic field?
Expert's answer
As F = BIL sin α, we can obtain&
B = F/ ILsin α = 0.04/(2*0.1) = 0.2 T
B = F/ ILsin α = 0.04/(2*0.1) = 0.2 T
