Understanding the Motor Effect and its Practical Application

The video tutorial explains the motor effects, where a conductor and a magnet exert force on each other. It covers how to calculate the magnitude of this force using the formula F = BIL, where B is the magnetic flux density, I is the current, and L is the length of the conductor. The direction of the force is determined using Fleming's left hand rule. An example is provided to illustrate the calculation of force and its direction. Finally, the motor effect is applied to a simple electric motor, demonstrating how forces cause the coil to spin.

What is the magnitude of the force acting on the wire in the example, and in which direction does it act?
