Determine the magnetic induction of the magnetic field acting on a conductor 20 cm

Determine the magnetic induction of the magnetic field acting on a conductor 20 cm long with a maximum strength of 0.26 N if the current in the conductor is 10A.

To find out the required field induction, consider the formula: FAmax = I * Bx * l, from where we express: Bx = FAmax / (I * l).

Const: FAmax – maximum force (Ampere force, FAmax = 0.26 N and sinα = 1); I – current (I = 10 A); l is the length of the conductor (l = 20 cm, which in the SI system is 0.2 m).

Let’s calculate: Bx = FAmax / (I * l) = 0.26 / (10 * 0.2) = 0.26 / 2 = 0.13 T.

Answer: The conductor must be in a field with an induction of 0.13 Tesla.
