a current-carrying wire is oriented at right angles to a uniform magnetic field. if the lenght of the wire is 0.50m and it experiences a force at 0.90n while carrying a current of 4.0a. what is the strength of the magnetic field?

  • physics -

    The answer is .45 T
    F = B(I)L
    B = F/(I)L
    B = .90/4(.5)
    B = .45 T
    (T is Teslas)
