Velocity can be calculated using the formula v = Bq/m, where v is the velocity, B is the magnetic field strength, q is the charge of the particle, and m is the mass of the particle.
The velocity of a particle is directly proportional to the magnetic field strength. This means that an increase in the magnetic field strength will result in an increase in the velocity of the particle.
No, velocity cannot be determined using only a magnet. A magnetic field is required to determine the velocity of a charged particle, and this magnetic field can be created using a magnet.
The direction of the magnetic field can affect the calculated velocity by either increasing or decreasing it. This is because the direction of the magnetic field determines the direction of the force acting on the charged particle, which in turn affects its velocity.
The units for velocity when using magnetism are meters per second (m/s). This is the standard unit for measuring velocity and represents the distance traveled per unit of time.
