c. Describe how to use right-hand rules to relate the directions of magnetic fields, currents, moving charges, and forces. (1 point) pls some one help me

We can remember this diagram using the right-hand rule. If you point your pointer finger in the direction the positive charge is moving, and then your middle finger in the direction of the magnetic field, your thumb points in the direction of the magnetic force pushing on the moving charge.

No because a circle or pie graph usually shows percentages you'd need a line graph
