nillan Learning Activity on the Sun, such as solar flares and coronal mass ejections, hurls large numbers of charged particles into space. When the particles reach Earth, they can interfere with communications and the power grid by causing electromagnetic induction. For example, a current of millions of amps (known as the auroral electrojet) that runs approximately 100 km above Earth's surface can be perturbed. The change in the current causes a change in the magnetic field it produces at Earth's surface, which induces an emf along Earth's surface and in the power grid (which is grounded). Induced electric fields as high as 6.0 V/km have been measured. We can model the circuit at Earth's surface as a rectangular loop made up of the power lines completed by a path through the ground beneath. We can treat the magnetic field created by the electrojet as being uniform (but not constant) and parallel to Earth's surface near the surface. Consider a 1.0-km-long stretch of power line that is…

As shown in the figure below, a circular ring with a radius of a is folded along a line across the diameter so that the two semicircles are perpendicular. In the magnetic field, this ring was rotated at a constant angular velocity over time, as shown in the figure. The axis of rotation is an extension of the fold-off line and is perpendicular to the magnetic field. The resistance of the ring is R. (1) Give a qualitative explanation of what will happen. (2)Find the current flowing through the ring. (3)What torque should be applied to the ring to allow it to rotate at a constant angular speed? (4)What do you have to do to turn it N round? (5) What energy changes from ring to heat? (6) How much energy changes from ring to heat? * I'll be so thankful and satisfied to get answer just least 3 of 6 questions..
