J7 A permanent magnet has a magnetic dipole moment of 0.140 A. m4. The magnet is in the presence of an external uniform magnetic field (provided by current-carrying coils) with a magnitude of 0.0800 T, which makes anangle of 21.0° with the orientation of the permanent magnet.(a) What is the magnitude of the torque (in N.m) on the permanent magnet?N.m(b) What is the potential energy (in J) of the system consisting of the permanent magnet and the magnetic field provided by the coils?

Given that,M=0.14A.m2B=0.08Tθ=21°We know that,Torque, τ=MBSinθ Equation 1put all known values in…

Part B Which of the four drawings is a correct force diagram for this problem? (Figure 2) a b C Submit Request Answer Choose a coordinate system for each body Newton's 2nd law, F = mã, is a vector equation. To add or subtract vectors it is often easiest to decompose each vector into components. Whereas a particular set of vector components is only valid in a particular coordinate system, the vector equality holds in any coordinate system, giving you freedom to pick a coordinate system that most simplifies the equations that result from the component equations. It's generally best to pick a coordinate system where the acceleration of the system lies directly on one of the coordinate axes. If there is no acceleration, then pick a coordinate system with as many unknowns as possible along the coordinate axes. Vectors that lie along the axes appear in only one of the equations for each component, rather than in two equations with trigonometric prefactors. Note that it is sometimes…

A plane leaves Seattle, flies 85.0 mimi at 20.0 ∘∘ north of east, and then changes direction to 51.0 ∘∘ south of east. After flying at 125 mimi in this new direction, the pilot must make an emergency landing on a field. The Seattle airport facility dispatches a rescue crew. A.) In what direction should the crew fly to go directly to the field? Use components to solve this problem. B.) How far should the crew fly to go directly to the field? Use components to solve this problem.
