Honors Assignment

1) Find the radius for a tritium nucleus moving with a v perp of 6 x10^6 m/s in a magnetic field of B = 6 Tesla.

Note w = omega in what follows.

2) Given that mw^2r=qwrB write an expression for w in terms of qB and m and then find w for an electron, for a deuterium and for a helium 4 nucleus, all in a B=4T magnetic field.

3) Given that B = u0 I/(2 pi r), where u0 = 4 pi x10^-7. How much current, I, must a wire carry to produce a 4 T field 2 m away from the wire?
