working. What do you think could be the possible reasons for this?

Answer:
Experiment with the compass in this tutorial to see how it responds to magnetic fields. To move the horseshoe magnet to a new location, click and drag it. To see how a compass behaves when there is no magnet nearby to affect it, click the Hide Magnet button. You can make it reappear by clicking the Show Magnet button. Notice that when the magnet is absent, the compass needle points north, but when the magnet is present, the needle points toward the magnet. This is because the compass needle is magnetized and mounted in a way that allows it to move in response to magnetic fields. When the horseshoe magnet is present, the north end of the needle (colored red) is attracted to its magnetic field and aligns itself so that it is pointing toward the object. The closer the magnet is to the compass, the more powerful the effect. Even when the magnet is removed, the compass is still being affected by magnetic forces – those associated with the Earth. These forces normally cause the

Answer:
may be there is some magnetic field exist in the lab due to which magnetic compass is deflected
