    Some more magnetic field/induction questions

    For 32.74, i don't know what equation you are using. but when i did it i also got 0.15 for u from the torque formula and then just substitute that into the z>>r equation B= (1.257 * 10^-6) (u) / (2 pi * z^3) where u is the magnetic dipole and z is the distance from the center...

    Some more magnetic field/induction questions

    to find the pitch ... took a while to figure this out. 1st find the frequency (f) f = qB / 2(pi)m , all these are known q=charge of electron, m=mass of electron B=electric field in T (dont forget to convert from mT) 2nd find the T (time) T= 1/f 3rd find the velocity in the vertical...
