Calculate the force between two magnetic dipoles with r spacing in the same direction.
Calculate the force between two magnetic dipoles with r spacing in the same direction.
Find the force of attraction between two magnetic dipoles a distance r apart. The dipoles are oriented so that the north pole of the first dipole faces the south pole of the second.
1. Looking at the force on a magnetic dipoles, there are two models which yield slightly different results a. The force on an electric dipole is F (p. V)Ë because it's made Z of two electric monopole charges. If magnetic dipoles were actually made of Magnetic monopoles (like in the Gilbert model) we would expect F (m V)B, which doesn't experimentally seem to match observations, but derive this equation from the Taylor series: у B(F)B(F)[- ") VB(") d Assume that...
The magnetic force on a positive particle is in the same direction as the magnetic field lines. True or false?
Arrange two electric dipoles with dipole moments qd nose to tail
at distance r (r ) d) along a line including their axis. Use
Coulomb’s law to show that the force between them varies as r4.
4. Arrange two electric dipoles with dipole moments qd nose to tail at distance r (r »d) along a line including their axis. Use Coulomb's law to show that the force between them varies as 1r

Two charged particles move in the same direction with respect to the same magnetic field. Particle 1 travels 3 times faster than particle 2. However, each particle experiences a magnetic force of the same magnitude. Find the ratio |q1|/|q2| of the magnitudes of the charges.
. Magnets consist of dipoles that orientate in the same direction south to give a magnet its magnetism. * True False
Two
cars are traveling with initial velocity V0 in the same direction,
with some initial spacing d between them. The first car suddenly
breaks to a halt. The car behind it also breaks after some time
lag
t,
with the same deceleration.
1)
Show the graph of distance versus time for both cars in the
scenario
2)
Show the graph of the minimum initial spacing d between the cars it
takes for them to never touch after breaking versus
time....
