7. Describe, qualitatively and quantitatively, the force on a current-carrying wire due to thepresence of an external magnetic field. Describe how to find the force on a charge moving ata given velocity, in the presence of an external magnetic field. Describe the "right hand rule". Describe in detail the path of a charged particle projected into a uniform magnetic field. Show how to calculate the torque on a current loop in the presence of an external magnetic field?What is meant by the magnetic dipole moment?
