Magnetic field of 10T directed vertically upward exerts a force on a particle having a charge of 1C moving toward 37° north of east at a speed of 1m/s.
Magnetic field of 10T directed vertically upward exerts a
force on a particle having a charge of 1C moving toward 37° north of east at a speed of 1m/s. The magnitude of the said force
must be
A uniform magnetic field exerts a force on a moving charge which
is equal to the charge times the vector product of the velocity and
the magnetic field. Can this force change the magnitude of the
velocity of the charge? Explain. Can both uniform electric and
magnetic fields exist (for non-zero fields) where the net force on
a charge is zero? If so, what are the constraints on the fields? If
not, why not?
3a) An electron is moving due north when it enters a magnetic
field directed downwards toward the ground. What is the direction
of the magnetic force on the electron?
b) The magnetic field strength 0.5 m away from a long straight
wire is 7.2 x 10-7 T. Calculate the current in the
wire.
c) A single-turn wire loop of radius 5 cm rests flat on a table
which is perpendicular to a magnetic field of strength 3.4 T. The
field...
