Flemings Left Hand Rule

The video tutorial explains Fleming's left hand rule, which uses conventional current to determine the direction of force in a magnetic field. It provides a step-by-step guide on how to position the fingers to identify the direction of force, with examples illustrating different scenarios. The tutorial also covers how forces act on a coil, leading to rotation, and concludes with a summary of the key points.

What does Fleming's Left Hand Rule help determine?

• The speed of light in a vacuum

• The resistance of a wire

• The direction of force on a wire in a magnetic field

• The amount of current in a circuit

In Fleming's Left Hand Rule, what does the first finger represent?

• The direction of the current

• The direction of electron flow

• The direction of the force

• The direction of the magnetic field

How should the second finger be positioned when the conventional current is coming towards you?

• Pointing towards you

• Pointing upwards

• Pointing away from you

• Pointing downwards

What happens to the force on the wire when the conventional current is reversed?

• The force is halved

• The force direction changes

• The force doubles

• The force remains the same

When a wire is wrapped into a coil, how do the forces on the coil halves affect its motion?

• The coil rotates

• The coil moves linearly

• The coil expands

• The coil remains stationary
