Explain why the aluminium coil in the moving coil galvanometer ( MCG ) rotates when current is passed through the hair springs​

This is due to the radial magnetic field lines created that cross this frame

• After rotation, the moving torque is created. And the torsion resistant wire creates the stopping torque that stops the motion.

Explanation:

answer: d. a cme increases the amount of energy in the solar wind

explanation:

coronal mass ejections, also called cmes, are large clouds of plasma and magnetic field that erupt from the sun. only when the cloud is aimed at earth will the cme hit earth and therefore cause impacts. high-speed solar wind streams come from areas on the sun known as coronal holes.
