Motion of a Charged Particle in a Uniform Magnetic Field A charged particle in uniform magnetic field which is perpendicular to its direction of motion travels in a circular path This is because th...
Measuring Magnetic Flux Density using a Hall Probe A Hall probe can be used to measure the magnetic flux density between two magnets based on the Hall effect It consists of a cylinder with a flat s...
Hall Voltage The Hall voltage is a product of the Hall effect Hall voltage is defined as: The potential difference produced across an electrical conductor when an external magnetic field is applied...
Calculating Magnetic Force on a Moving Charge The magnetic force on an isolating moving charge, such an electron, is given by the equation: F = BQv sinθ Where: F = force on the charge (N) B = magne...
Magnetic Flux Density Definition The magnetic flux density B is defined as: The force acting per unit current per unit length on a current-carrying conductor placed perpendicular to the magnetic fi...
Fleming's Left-Hand Rule The direction of the force on a charge moving in a magnetic field is determined by the direction of the magnetic field and the current Recall that the direction of the curr...
Force on a Current-Carrying Conductor A current-carrying conductor produces its own magnetic field When interacting with an external magnetic field, it will experience a force A current-carrying co...
Magnetic Field Definition A magnetic field is a field of force that is created either by: Moving electric charge Permanent magnets Permanent magnets are materials that produce a magnetic field A st...
The Time Constant The time constant of a capacitor discharging through a resistor is a measure of how long it takes for the capacitor to discharge The definition of the time constant is: The time t...
