- The earth’s magnetic field varies from point to point in space. Does it also change with time? If so, on what time scale does it change appreciably?2. A circular antenna of area 5m² is installed at a place in Marawi. The plane of the area of antenna is inclined at 45° with the direction of the Earth's magnetic field. If the magnitude of the Earth's field at that place is 39889.7nT find the magnetic flux linked with the antenna.Would the location of the magnetometer on the phone have a significant effect on the measurement of Earth’s magnetic field? Explain why or why not.
- How do ferrite beads on cables help in reducing electromagnetic interference?In the context of Electromagnetism - define the terms ”birefringent” and ”uniaxial”2. Imagine that magnetic fields could be produced by monopoles--for example, a single isolated north pole. How would you detect this with a compass? Sketch what you would see
