Questions from Anil Ahlawat Solutions for Chapter: Magnetic Effects of Electric Current, Exercise 1: EXERCISES with Hints & Solutions
A wire is placed between the magnetic poles as shown in figure. In which direction does a force act on the wire?
Consider the arrangement shown in figure in which the North pole of a magnet is moved away from a thick conducting loop containing capacitor. Then excess positive charge will arrive on
An electric current passes through a straight wire. If magnetic compasses are placed at the points and as shown. Then,
Match the column I with column II and select the correct option from the codes given below.
| Column | Column | ||
| Right hand thumb rule | Application of electromagnetic induction | ||
| Fleming’s right hand rule | Direction of magnetic field due to current in wire | ||
| Current carrying solenoid | Similar to bar magnet | ||
| Electric generator | Direction of induced current | ||
Read the passage carefully and answer the following questions.
Three specimens of magnetic material were tested using the apparatus shown in the diagram. When the switch is closed, the specimen picks up some of the iron nails but when the switch is opened, many or most of the nails fall off. The number of nails picked up and left on were found for three specimens. The table shows the results.
| SPECIMEN | NUMBER OF NAILS PICKED UP | NUMBER OF NAILS RETAINED BY THE SPECIMEN |
