Solution

It is given that a thick wire is hanging form a wooden table. An anticlockwise magnetic field is needed to be produced around the wire by passing current through it using a battery. Then, according to right hand thumb rule, current should pass through the wire from bottom end to top end. To execute this flow, positive terminal of the battery should be connected to the bottom end and negative terminal of battery should be connected to the top end because current flows from positive terminal to negative terminal.
