Resultant force acting on a diamagnetic material in a magnetic field is in direction

If the magnetic force on a moving charged particle in a magnetic field becoms ______ the direction of motion of the particle, or its opposite direction, indicates the direction of magnetic field. [Fill in the blank

The direction of force acting on a current carrying conductor at right angles to a magnetic field is given by

In which condition is the magnetic force acting on a given current - carrying rod placed in a magnetic field maximum and in which condition would the magnetic force not act on the rod ? (Assume that the current through the rod and the strength of the magnetic field are not changed).

What happens to the force acting on a current-carrying conductor placed in a magnetic field when : a] current in conductor increases ? b] length of the conductor increases ? c] direction of the current and magnetic field are reversed ? d] direction of the current is reversed without changing the direction of magnetic field ?

What is the direction of the magnetic force acting on a current - carrying wire placed in a magnetic field ?
