Momentum and magnetic fields are both vector quantities. If two bodies with the precise mass and speed collide head on (θ = 0), then momentum is conserved (they come to a complete stop) and energy is conserved (the kinetic energy is changed to other forms). What then happens in the case of two identical strength magnetic fields that meet head on? A gauss meter placed precisely in between them would read zero if measured in the same direction of the field. Is the energy conserved simply by changing direction? This is an oxymoron as energy is not a vector quantity. Thank you.
