Draw a sketch of the magnetic field around a bar magnet. - Leaving Cert Physics - Question i - 2007

To illustrate the magnetic field around a bar magnet, follow these steps:

1. Draw the Bar Magnet:

   • Begin by sketching a horizontal rectangle to represent the bar magnet. Label one end as 'N' for the North pole and the other as 'S' for the South pole.

2. Indicate the Magnetic Field Lines:

   • Draw several curved lines that originate from the North pole and extend towards the South pole. These lines should curve around the magnet, showing the path of the magnetic field.

3. Direction of the Field Lines:

   • Use arrows on the field lines to indicate the direction of the magnetic field. The arrows should point away from the North pole and towards the South pole.

4. Label the Field Lines:

   • You may choose to label the field lines as 'Magnetic Field Lines' or simply 'B' to represent the magnetic field.

5. Ensure Representation of Field Lines:

   • Make sure at least two clear field lines are visible in your sketch for a complete representation.

This sketch should clearly show the relationship between the magnetic field and the bar magnet itself.
