In this section, we explore how a solenoid generates a magnetic field when electric current passes through it. The field lines produced are similar to those of a bar magnet, forming parallel lines inside the solenoid, which indicates a uniform magnetic field. Applications include creating electromagnets.
The magnetic field produced by a solenoid is a critical aspect of electromagnetism. A solenoid is defined as a coil of many circular turns of insulated copper wire wrapped closely in the shape of a cylinder. When current passes through the solenoid, it generates a magnetic field with distinct properties:
In summary, understanding the magnetic field created by a solenoid leads to the realization of its vast potential in technology and its fundamental role within the framework of electric currents and magnetism.
Solenoid: A coil that can produce a magnetic field.
Electromagnet: A temporary magnet created by electric current.
Uniform Magnetic Field: A steady magnetic field present within a solenoid.
In a coil we find a way,
A scientist once wrapped a wire around a tube. When he turned on the current, he discovered it had turned into a magnet! This became the solenoid that helped build electric doors.
