A circular loop of wire with ra dius 8.0 cm carries a current of 0.20 A. A vec- tor of unit length and parallel to the dipole mo- ment ii of the loop is 0.60i 0.80j. If the loop is located in a uniform magnetic field given by B (0.25T) (0.30T)k, what is the orientation energy of the loop? a) 0 J b) -6.0 x 10-4 J c) 2.5 x 10-4 J d) 3.2 x 10-4 J e) 5.1 x 10-3 J

B= -6.0×10⁻⁴J

r=rho l/a where a is the area, l is the length and rho is resistivity so the greater the area the lesser the resistance thats why the earth pin is thicker bcos current follow the shortest path, so less resistive .

in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.
