Given a long thin solenoid with a point charge of e. Initial conditions, e is at rest, the solenoid is on, i.e., there is current running through it, and the magnetic field outside is essientally 0 due to the length of the solenoid. Final conditions: the solenoid is turned off, i.e. current is zero, the charge then gets a kick so that its velocity is not zero. The magnetic flux of the induction coil is zero. Is the angular momentum conserved?

2. Relevant equations

L = r X mv

3. The attempt at a solution

Well, I'm supposed to "analyze" this problem from the points of view of the Newtonian (ma type of equations) and the Hamiltonian formulas. Anyone know how I should get started, this problem kinda confuses me a bit.
