Question

How come electricity can be insulated but not magnets?

Answer 1

Electricity always flows in one direction, negative to positive, magnetic fields flow different paths, making electricity much easier to contain then magnetic forces  

Answer 2

An electrical conductor can be shielded from the influence of magnetic fields by enclosing the conductor in a metallic sheath, and ground the sheath at both ends.

Answer 3

Sure you can "insulate" magnets, just put them inside a steel can or steel foil.   The magnetic field can't get out.  Not very useful.  More likely, insulate a room magnetically so you can perform experiments free of the earth's magnetic field or avoid damaging outside instruments with heavy magnetic fields.

Answer 4

The flow of electrons needs a conductive path (metals) to go through, but magnetic flux lines don't need a conductive path at all.  Scientists can say what happens and can duplicate it, but still do not fully understand it.

They understand everything about gravity, except how to duplicate it.

Answer 5

Magnetic field can be "insulated" sort of.  A permanent magnet will float /levitate above a superconductor because a superconductor does not allow magnetic field lines to penetrate.  (there are inexpensive kits available where you can demonstrate this yourself if you have some liquid N2 to cool the "hi temp" superconductor wafer)   Magnetic field can also be controlled or shaped by magnetic inductors.  Electrical transformers are made much more efficient by clever design using transformer steel (alloys that are metallurgically designed to concentrate the magentic field where the transformer coils are.   hope this helps
