Need help with the blank ones.

A bar magnet is placed a distance _ = 15.6 cm to the right of a compass that originally points North, as shown in the diagram. After the magnet is placed next to the compass, the needle of the compass deflects 78.40 to the West. Note that the diagram is not drawn to scale . AN N Magnet W S L From the perspective of the diagram, the North Pole of the magnet is to the Left What is the magnitude of the magnetic moment of the bar magnet? Take the magnitude of Earth's magnetic field to be 2 x 10 T. A . m What is the magnetic field due to a very very long wire with current 7 A at a perpendicular distance 0.4 m away from the wire ? At a particular instant, a proton, far from all other objects, is located at the origin. The proton is traveling with velocity (-8 x 10, 0, 0)m/s. Consider the electric and magnetic fields at observation point (7 x 10 10, 4 x 10 , 0)m caused by this proton. What is the electric field at the observation point? 0 0 What is the magnetic field at the observation point? 0 0 At one instant, a proton is at the origin with a velocity m/s. At the observation location m: What is the electric field due to the proton? nN What is the magnetic field due to the proton
