The strongest macroscopic B-field produced in a laboratory is the 45.0 T one at the National High Magnetic
Field Laboratory in Tallahassee. Suppose that the 45.0 T field is uniform and points into the page. How fast
would a 1.00 kg insulating ball carrying 1.00 mC of positive charge have to move to produce a Lorentz force
equal to its weight?

Consider a system of charges and currents. The work done per second by the fields on charge q
is:
F.ö = qü · (Ë + õ x B) = qū · Ë
Where F is the Lorentz force.
The work done per second per unit volume is:

By conservation of energy, the rate of change of the energy density in the electric and magnetic
fields is therefore:

- = A particle of mass m and charge q is in a room that is affected by a constant magnetic field with vector B B2 as well as a constant gravitational field with vector g=-gŷ. Particles are initially held at rest, until one day they are released and fall under the influence of gravity. The fall of the particle certainly causes the particle to have a number of speeds, and this of course causes the particle to experience Lorentz forces at the same time as the gravitational force that affects the particle. Due to the influence of the Lorentz force, the particle will experience a bend so that there is a condition where the particle no longer has the velocity component ŷ and begins to move upward, say this state occurs at the lowest point of the particle's path. a) Determine the velocity of the particle at its lowest point. b) Same as part a), only if initially the particle is thrown downward with initial velocity u Kindly answer these questions.
