what is a solenoid? draw a diagram with a solenoid connected in a circuit. How can you increase the strength of a solenoid?
answer if you know .don't answer if you don't know
Answers
the iron bar of electromagnet is called solenoid to increase the strength of the solenoid either increase the intensity of current it or increase the number of turns of the copper wire of the electromagnet.
Answer:
The solenoid is a device with a long cylindrical coil of wire having a large number of turns fixed together very tightly. It is included in a coil of wire and a moveable plunger which is also known as an armature.
The condition for being a solenoid is that the length of the coil must be greater than its diameter. The magnetic field around a current carrying solenoid is represented in the diagram.
This may look very much similar to that of a bar magnet. If a soft iron rod is kept inside the solenoid, it will behave like an eletromagnet. Generally the soft iron metal is being used as a core in the solenoid in order to create strong magnetism.
The strength of a magnetic field formed by current carrying solenoid can be increased by--
• Increasing the number of turns in the solenoid,
•increasing the current through the coil.
