Question 18
Easy

A straight wire carrying a current is placed at right angles to a magnetic field.

  • The force on the wire is 0.24 N.
  • The current in the wire is 1.5 A.
  • The magnetic flux density is 0.40 T0.40\text{ T}0.40 T.

Calculate the length of the wire that is in the magnetic field.

Use the equation:

force=magnetic flux density×current×length \text{force} = \text{magnetic flux density} \times \text{current} \times \text{length} force=magnetic flux density×current×length
