Question

A straight wire 15cm long, carrying a current of 6.0A is in a uniform field of 0.40T. What is the force on the wire when it is at right angle to the field

Options

A) 0.46N

B) 0.35N

C) 0.36N

D) 0,24N

The correct answer is C.

Explanation:

F = BIL = 0.4 x 6 x \(\frac{15}{100}\)

= 0.36N

    2. F = B I L

      F is force measured in newtons (N)
      B is flux density (the strength of a magnetic field I.e No. of magnetic lines of force from magnet per unit area) measured in teslas (T, named after Nikola Tesla)
      I is current measured in amperes (A)
      L is the length of conductor in the magnetic field measured in metres (m)
