Introduction

  • The term attractive impact of electric flow implies that an electric flow streaming in a wire creates an attractive field around it. 
  • It means electric current can produce magnetism.
  • A magnet is an item which draws in bits of iron, steel, nickel and cobalt. the magnet has two poles north and south.
  • Unlike poles repel each other and similar poles attract each other.
  • The space encompassing a magnet in which attractive power is applied is called an attractive field. A magnetic field is described by drawing magnetic field lines.
  •  Attractive field lines begin from the north shaft and end at the south post. 
  • They come more like each other close to the posts of magnet yet they are isolated at different spots.
  • The attractive field lines never cross each other in light of the fact that the resultant power on a north shaft anytime can be just one way. Be that as it may, in the event that two attractive field lines meet, at that point the subsequent power on a north shaft set at the purpose of convergence will be along with two bearings, which is unimaginable.
  • Inside a magnet, the direction is south to north and outside the magnet, the direction is north to south.
  • Crowded magnetic field lines indicate stronger magnetic fields.

Magnetic Field Patterns Produced By Current-Carrying Conductors having Different Shapes

Straight Conductor: The Magnetic Field Lines around a straight conductor are concentric circles.At the point when the current in the wire streams an upward way then the lines of the attractive field are an anticlockwise way.   If the direction of current is reversed then the direction of current is reversed, the direction of magnetic field lines is also reversed. Consequently, the attractive field delivered by a straight conduit is straightforwardly corresponding to the present going in the wire and contrarily relative to the separation of that point from the centre.

  • Right, Hand Thumb Rule- According to this rule, if we are holding the current-carrying wire in our right hand so that the thumb points in the direction in the of current, at that point the bearing where our fingers surround the wire will provide the guidance of attractive field lines around the wire. 
  • Circular Loop-  The attractive field lines are roundabout close to the current conveying, the concentric circles become greater and greater. In the middle, the attractive field lines are straight.  At the centre, all magnetic field lines are in the same direction due to which strength of the magnetic increases. The magnitude of the magnetic field is directly proportional to the current passing through the circular wire and inversely proportional to the radius of the circular loop.
  • Clock Face Rule- If the direction of current is clockwise, that face of circular wire will act like the south pole. If the direction of current is anticlockwise, that face will act as a north pole.
  •  Magnetic Field In Solenoid- The solenoid is a long loop containing an enormous number of close turns of protected copper wire. The attractive field delivered by a current conveying is like the attractive field created by a bar magnet. The attractive field lines inside a solenoid are as straight lines which demonstrate the quality of the attractive field is the equivalent at all focuses inside the solenoid.

The strength of the magnetic field produced by solenoid depends on a number of turns in the solenoid, the strength of current, nature of core material used in making solenoid.

Electromagnet and Force in a Magnetic field

  • An electromagnet is a magnet consisting of a long curl of protected copper wire folded over a delicate iron centre that is charged just when the electric flow is gone through it. It works on the magnetic effect of current.
  • An electromagnet is a temporary magnet that can produce a very strong magnetic force.
  •  At the point when a current conveying conductor is set in an attractive field, mechanical power is applied on the conductor which makes it move. 
  • The direction of force acting on a current-carrying conductor or wire placed in a magnetic field is perpendicular to the direction of the current and direction of the magnetic field.
  • Fleming’s left-hand rule for the direction of force states that” Hold the forefinger, centre finger and thumb of your left hand at right angles to one another. Change your turn so that the index finger focuses toward the attractive field, the middle finger focuses toward current then the bearing where the thumb focuses provides the guidance of power following up on the conductor.   
  • The production of electricity from magnetism is called electromagnetic induction and this process led to the construction of generators for producing electricity at power stations.
  • A galvanometer is an instrument which can identify the nearness of electric flow in a circuit.  The direction of the induced current can also be reversed by reversing the direction of the magnetic field.
  • The creation of electric flow by moving a magnet inside a fixed curl of a wire is likewise an instance of electromagnetic enlistment. The condition vital for the creation of electric flow by electromagnetic acceptance is that there must be a relative movement between the curl of wire and magnet.
  • Flemmings right-hand decision states that “Hold the thumb, the index finger and the inside finger of your correct hand at right edges to each other. 
  • Adjust the hand in such a way that the forefinger points in the direction of the magnetic field, and the thumb points in the direction of motion of current.  At that point, the heading where the focus finger focuses provides the guidance of actuated current in the conductor.
