- A wire carrying a 5 A electric current is placed in a 2 T magnetic field. If there is no force exerted on the wire, what is known about the directions of the current and the magnetic field? there is no current in the wire the torque on the wire cancels out the force due to the magnetic field the wire is parallel to the magnetic field the induced magnetic field around the wire cancels out the effect of the applied magnetic field the wire is perpendicular to the magnetic field49.Explain the difference between similar (uniform) and dissimilar (non-uniform) magnetic fields. Please answer. ASAP
