Question

The relationship between magnetic force and magnetic pole strength is similar to the relationship between which of the following?. A) force, mass, and distance as in Newton's law of gravity.B) All of these.C) current, voltage, and resistance as in Ohm's law.D) Two of these.E) force, charge, and distance as in Coulomb's law

Answer 1

So what do you think, Christy?

Answer 2

all of these

Answer 3

Hardly. It seems to me Coulombs law and the Magnetic strength equation are very similar.

Answer 4

1. The magnitude of magnetic force
F =I•L•Bsinα.
2. Newton's law of gravity
F= G •q1•q2/r^2
3. Ohm’s Law
U =I•R
4. Coulomb’sLaw
F= G• m1•m2/r^2
I believe that similar are #1 and #3, as #2 and # 4 are inverse proportional laws
