Question

(a) Draw the pattern of magnetic field lines in and around a long current carrying solenoid. (b) Indicate (i) polarity of each end : (ii) direction of magnetic field inside the solenoid ? (c) State one important feature of the magnetic field obtained inside the solenoid. (d) Write one use of solenoid. (e) List two important properties of magnetic lines of force.

Answer 1

Answer:

Explanation:

Theory: A coil of many circular turns of insulated copper wire wrapped closely in the shape of a cylinder is called a solenoid. The pattern of the magnetic field lines around a current-carrying solenoid is illustrated in Fig. ... The field lines inside the solenoid are in the form of parallel straight lines.
