The deflection of the needle demonstrates the interconnection between electricity and magnetism, indicating that these two phenomena are linked.

Hans Christian Oersted accidentally discovered that a compass needle deflected when an electric current passed through a nearby metallic wire.

Oersted demonstrated that electricity and magnetism are related phenomena, providing a crucial foundation for understanding electromagnetism.

Non-biodegradable substances are materials that cannot be broken down by biological processes. They may persist in the environment for a long time, potentially causing harm to various members of the ecosystem due to their inert or toxic nature.

Biodegradable plastics are a new type of plastic designed to break down more quickly and completely than traditional plastics. They are generally more environmentally friendly as they decompose into non-toxic components. However, the actual impact on the environment can vary ...
