Solenoid in Physics. A solenoid is a basic term for a coil of wire that we use as an electromagnet. We also refer to the device that can convert electrical energy into mechanical energy as a solenoid. Actually it generates a magnetic field for creating linear motion from the electric current. With the use of a magnetic field.
In a solenoid, poles can be considered to be lying at the edge. b) The magnetism retains in the bar magnet naturally but in the solenoid, the magnetism is there so long current flows through it. c) A magnetic field of a bar magnet emanates from throughout the body of the magnet, with more intensity at the poles.
Jan 1, 2020 · A coil of many circular turns of. insulated copper wire wrapped closely in the shape of a cylinder is called solenoid. Explanation: The field line inside the solenoid is parallel straight lines. A strong magnetic field inside a solenoid can be produced by using soft iron or increasing no of turns. Thus it is known as electromagnet.
It is clear that self inductance of solenoid depends upon the following factors: (1) On relative permeability of material inside the solenoid: If a soft iron core placed inside the solenoid, the magnetic flux linked with the solenoid increased hence, self inductance of the solenoid will also increases. (2) On total number of turns in solenoid ...

(a) What is a solenoid ? Draw a sketch to show the magnetic field pattern produced by a current-carrying solenoid. (b) Name the type of magnet with which the magnetic field pattern of a carrent-carrying solenoid resembles. (c) What is the shape of field lines inside a current-carrying solenoind ?
Q 4. Define the term 'mutual inductance' between the two coils. Obtain the expression for mutual inductance of a pair of long coaxial solenoids each of length l and radii r1 and r2(r2>> r1). Total number of turns in the two solenoids are N 1 and N 2 respectively. View Solution.
The solenoid engine can cause zero atmospheric pollution. These engines are very useful as an alternative to fossil fuels. The engine has more efficiency whereas the torque produced is less. The reaction time needed for the solenoid engine is very quick. The core of the solenoid engine is useful for applying mechanical force to the valve.
A solenoid is a long coil made up of insulated copper wire having large number of closed turns. The magnetic field lines around a solenoid are same to that of a bar magnet. The field lines inside solenoid are parallel to each other which indicates that the magnetic field inside the solenoid is same at every point.
