 Part 2 Page 81 Very Short Answer Type Questions 1.Which effect of current can be utilized in detecting a current-carrying wire concealed in a wall? The effect of a current-carrying wire on a nearby magnetic compass needle can be utilized in detecting the wire concealed in a wall. 2.What conclusion do you get from the observation that a current-carrying wire deflects a compass needle placed near it? The observation suggests that an electric current produces a magnetic field around it. 3.Name the scientist who discovered the magnetic effect of current. Hans Christian Ørsted. 4.State qualitatively the effect of inserting an iron core into a current-carrying solenoid. Inserting an iron core into a current-carrying solenoid enhances the magnetic effect, resulting in a stronger overall magnetic field. 5.Name the rule for finding the direction of magnetic field produced by a straight current-carrying conductor. The Right-Hand Rule. 6.State the form of magnetic field lines around a straig...
