A charged particle placed in a magnetic field experiences a force that causes it to deflect in the direction of force. General Physics. When the wire is coiled into a spiral tube, it is called a solenoid . The relationship between the direction of the lines of force and of the current is expressed in Right hand grip rule. If you put the thumb of your right hand in the direction of the current flow and encircle the wire with your fingers, as shown below, the direction of those fingers will correspond to the direction of the magnetic field. Look at the ends of the coil from the outside; the direction of the current follows the direction of the letters N and S for north and south (see Figure 1). 2. Answer 1: To find the polarity of a solenoid, you can use the right-hand rule for current (or left-hand rule for electrons since they go in the opposite direction to the current). In solenoid the direction of the magnetic field can be found by applying the right hand grip rule. The right hand rule or Maxwell's corkscrew rule tells us to point our thumb in the direction of the current, and thus wrapping our fingers will show us the flow of the magnetic field. According to Faraday's law of electromagnetic induction, when a conductor moves through a magnetic field, an electric current is induced in it.Fleming's right-hand rule is used to determine the direction of the induced current. (b) the right hand grip rule (i) for a solenoid If you imagine gripping the solenoid with your right hand so that your fingers follow the direction of the current then your thumb will point towards the NORTH end of the electromagnet (see Figure 2).

It is often useful to be able to remember which way the field points (the direction a compass needle will point) when placed near the wire. Found the tutorials super useful? According to this rule if the fingers of the right hand grip the . A long closely wound helical coil is called a solenoid. You must note that because the current travels through a coil, charge enters through the negative terminal from one end of the wire and flows in a circular fashion through the coil to exit from the positive terminal on the opposing end of the wire. Magnetic field due to solenoid (right hand grip rule): 1. ii) Electrical method - place the magnetic material in a coil (solenoid) and pass direct current through it. The best way to apply the direction of the Lorentz force is by using Fleming's left (or right) hand rule. Switch on the d.c supply.
