Question

When using the right-hand rule to determine the direction of the magnetic force on a charge, which part of the hand points in the direction that the charge is moving?

Answer 1

Answer:

The correct answer is the thumb of the right hand.

Explanation:

The Force will follow Lorentz's law, a vectorial product: F= q*v x B, where:

q is the charge of the particle.

v is its velocity.

x indicates the vector product.

B is the magnetic field.

Being a vector product F the plane formed by v and B will be perpendicular. To determine the sense we will apply the variant of the rule of the right hand. The fingers of the right hand without the thumb run from vector v to vector B, so in this case, the force will have a sense upwards. It must be said that the rule always indicates the direction of the positive charge if the charge is negative the direction of F is inverse (downwards).

Have a nice day!

Answer 2

Your thumb points in the direction of the charge.
