In the dark knight rises batman used his EMP gun to stop the bad guys. I was wondering if a magnetic field can be directed or channeled and also if it can be blocked with any material besides lead. I know it's used coils and capacitors to releases a electromagnetic pulse to short of the electronics.

Electromagnetic pulses can be shielded with a conductor, silver is the best, copper is very good and aluminium is the lightest.
A constant magnetic field can only be shielded with a magnetic material shuch as iron.

Look up Faraday cage.
