A stationary proton is in a uniform magnetic field of 0.20 t. What is the magnitude of the magnetic force on the proton is zero.
Magnetic Field is the region around a magnetic material or a moving electric charge within which the force of magnetism acts.
Magnetic field, B = 0.2 T
Magnetic Force, F = B × v × q,
Here, v = speed = 0,
Hence, the magnetic force on the proton by the above formula,
⇒ F = B v q = 0.
What is the shape of magnetic field lines?
The shape of the magnetic field lines is of around a straight current carrying conductor.
