Answer 1

Depending where you are the earth’s magnetic field is around 50 micro teslas.
A tesla being a unit of how magnetic something is.
Your average fridge magnet clocks in at around **5,000** micro teslas.
And a lot computer stuff uses magnets in the million of micro teslas.

So all of it is much much stronger than the earth’s magnetic field.
