A EMP pulse is a strong enough to overcome most faraday cages. The metal in the cage can't conduct enough current to substantially reduce the magnetic field.

Aren't they intertwined? That's why you can put a loop around a wire and determine if it's live.
Current produces magnetism.

 I think what he wants is a Faraday cage. Easier to apply to the outside of the van in a net-like fashion and when not moving.
 This is how a microwave keeps us from being baked while we watch our food.
It's quite possible I totally misunderstood emp through!

 Cheers,
Harry
