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

bobpursley,
So what do you think, Christy?

physics 
Christy,
all of these

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

physics 
Elena,
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
