### direction of magnetic field lines

2)Magnetic field lines are closed curves. This is something rarely covered explicitly, but I have always found to be essential to intuitively understanding the electromagneric field. 3)If magnetic field lines are parallel and equidistant, they represent zero field strength. Magnetic Field Generated by Current: (a) Compasses placed near a long straight current-carrying wire indicate that field lines form circular loops centered on the wire. The magnetic lines of force are the lines drawn in a magnetic field along which a hydrothetical north magnetic pole would move if it is free to do so. Example: Find the force on a moving particle due to the magnetic field of a wire F = qv X B = q v B sin(a) A = 90 degrees F = q v B = q v By the right hand rule the force points towards the wire. Magnetic field lines emerge from the North pole and merge at â¦ This activity will help you do just that. As shown in Figure 20.9 , the direction of magnetic field lines is defined to be the direction in which the north pole of a compass needle points. The field lines emerge from the north pole (N), loop around to the south pole (S), and continue through the bar magnet back to the north pole. The direction of a magnetic field at a point is determined by placing a small compass needle. Great question! If you point your left thumb in the direction the electrons are flowing, your fingers will curl in the direction of the magnetic field. The magnetic field lines point in the direction where a magnetic force can never be. (b) (c) The properties of magnetic field lines are as follows. The direction of the magnetic field is taken to be the direction in which a north pole of the compass needle moves inside it. Magnetic fields are invisible. Field lines outside the solenoid are similar to that of a bar magnet, and it behaves in a similar way â as if it had a north pole at one end and south pole at the other end. A small compass will point in the direction of the field line. Depends on what you mean. Magnetic field lines are some dosed curved lines drawn on magnetic field and tangents are drawn on them at any point gives the direction of magnetic field at that point. The N - pole of compass indicates the direction of magnetic field at that point. Inside the magnet, the direction of field lines â¦ The direction of a magnetic field at a point is the direction of the resultant force acting on a hypothetical north pole placed at that point. Therefore it is taken by convention that the field lines emerge from north pole and merge at the south pole. * 1)The direction of magnetic field at a point is taken to be the direction in which the north pole of a magnetic compass needle points. (b) Right hand rule 2 states that, if the right hand thumb points in the direction of the current, the fingers curl in the direction of the field. Which of the following statements is incorrect regarding magnetic field lines. Magnetic field lines have several hard-and-fast rules: The direction of the magnetic field is tangent to the field line at any point in space. A small compass will point in the direction of the field line. The field lines emerge from the north pole (N), loop around to the south pole (S), and continue through the bar magnet back to the north pole. As with electric fields, the pictorial representation of magnetic field lines is very useful for visualizing the strength and direction of the magnetic field. But wouldnât it be cool if we could find out how to show the direction of magnetic field lines? You canât see them, but you can see what they do, like attract a paper clip or push another magnet away. The field lines in this region are parallel and closely spaced showing the field is highly uniform in strength and direction. â¢Curl fingers to the direction of the magnetic field â¢Thumb points in the direction of the force .
