Answer #1

1. Magnetic field is present alongside a current carrying wire (biot-savart law). Also, changing electric field produces a magnetic field (roughly deduced from ampere's law).

Hence, electric current or changing electric field would be the correct choice.

2. A charged object attracts another object of opposite charge as well as neutral objects.

Since , the correct statement would be neutral objects as well charged objects but out of the given options "neutral objects but not neutral particles" will be the most suitable one.

A TMS (transcranial magnetic stimulation) device creates very rapidly changing magnetic fields. The field near a typical pulsed-field machine rises from 0 T to 2.5 T in 200 ?s. Suppose a technician holds his hand near the device so that the axis of his 1.8-cm-diameter wedding band is parallel to the field. What emf is induced in the ring as the field changes? If the band is made of a gold alloy with resistivity 6.2×10?8??m and has a cross-section area...
