Question

Among the the 3 wires AB, BC and AD, which of the following wire(s) will generate magnetic field?
​

Answer 1

ab

Explanation:

this was most easy question please marked or very good

Answer 2

AMONG THE 3 WIRES -THE WIRE AB WILL GENERATE A MAGNETIC FIELD.

• The law actually says that a current-carrying conductor produces a flux since resistors don't seem to be metals so that they don't produce flux. Current passing through a conductor produces a field of force.
• Resistors are basically non-conductors that resist the flow of current (not the current).
• A wire-carrying electrical phenomenon will produce a flux with closed field lines surrounding the wire.
