Integrating Electromagnetism
• The force on a charge in a magnetic field
• The force on a current carrying wire.
• The induced voltage in a moving wire
are often taught as separate phenomena….
The first video shows the force on an electron moving perpendicular to a magnetic field.
• Lorentz 1.MOV
The electron is pushed to the right (direction given by LHS rule).
The second video shows the force acting on a metal rod carrying a current across a magnetic field.
• Lorentz 2.MOV
The force on the electrons (and hence the rod) is given by the LHS rule.
The third video shows the voltage induced in a metal rod moving perpendicular to a magnetic field.

• Lorentz 3.MOV
The force on the electrons and thus the polarity is given by the LHS rule.
