i think because magnet a is twice as strong, that magnet b is half of its strength.
also i forgot a few parts of the question that might help
it has twice the magnetic field strength.
well I'm not exactly sure. I'm looking in the chapter of magnetism in my book and i don't see any forumla's. its weird. i went back a chapter and found coulombs which deals with force=(k)(q1q2)/d^2.
i wasn't sure if it was right or now. if you could help me on a formula i could try and solve...
Magnet A has twice the magnetic field strength of magnet B (at equal distance) at a certain distance and pulls on the magnet B with a force of 30N. Determine the force with which magnet B pulls magnet A.
Could someone help me. I'm just starting physics in hs.

how much greater is the angular momentum of the Earth orbiting about the sun than the moon orbiting about the earth? (using a ratio of angular momenta)
angular momentum = rotational inertia x rotational velocity
