Describe an activity to show that a magnet has maximum strength at its poles. 2. Draw an electric circuit using the symbols for different components. Also write what happens if a magnet is broken in two pieces. 3. Why can't plastic be the main material in conducting wires? 4. Name different shapes in which magnets are available.
Understand the Problem
The question is asking for detailed answers regarding the behavior and properties of magnets, electric circuits, and related concepts, indicating a need for explanation and understanding of these topics.
Answer
1. Iron nails gather at a bar magnet’s ends. 2. Circuit: battery, resistor, switch; broken magnet makes two smaller magnets. 3. Plastic is an insulator. 4. Shapes: bar, horseshoe, disc.
-
To show a magnet's maximum strength at its poles, place several iron nails near a bar magnet; most will be attracted to the ends.
-
A basic electric circuit includes symbols for a battery, resistor, and switch. Breaking a magnet results in two magnets, each with a north and south pole.
-
Plastic is not used for conducting wires because it is an insulator and does not allow electrical current to pass through.
-
Magnets are available in various shapes such as bar, horseshoe, disc, and ring magnets.

More Information
When a magnet is broken, each piece retains its own north and south poles due to the alignment of magnetic domains.
Tips
Ensure circuit symbols are correctly used; remember plastic insulates.
