Magnetic force on a moving charge?

Hi, when a charged particle is moving through a magnetic field, it does not matter if the charge is positive or negative. The magnetic force on the charge will still be in the same direction. Is this correct?

No. Magnetic force is opposite for the charges. The Right hand rules help dictate the force. I usually just use the right hand rule and if it's an electron I flip the direction. Magnitude is negative I believe.

From what I can remember as well, positive charge = counter clockwise, negative charge clockwise.

Yep! using RHR#1...Everything is the same, but for electrons, you flip the direction for the force.

Magnitude of the force is the same. Direction is opposite. Flip the right hand rule when dealing with electrons. Remember any type of force is a vector and has both magnitude and direction.
