Question

what is the solenoid?​

Answer 1

Explanation:

• The solenoid is a long cylindrical coil of wire consisting of a large number of turns bound together very tightly.
• The length of the coil should be longer than its diameter.
• Magnetic field around a current carrying solenoid is shown in figure. These appear to be similar to that of a bar magnet.
• When soft iron rod is placed inside the solenoid, it behaves like an electromagnet. The use of soft iron as core in the solenoid produces the strong magnetism .

Answer 2

Answer:

A solenoid is a type of electromagnet, the purpose of which is to generate a controlled magnetic field through a coil wound into a tightly packed helix. The coil can be arranged to produce a uniform magnetic field in a volume of space when an electric current is passed through it.
