Do magnetic lines of force really exist?
To describe the phenomena related to magnets, lines are used to depict the force existing in the area surrounding the magnet. These lines are called the magnetic lines of force. These lines do not exist actually, but are imaginary lines that are used to illustrate and describe the pattern of the magnetic field.
Where are the lines of force most concentrated?
the field lines come out of the north pole and go into the south pole. the field lines are more concentrated at the poles.
Why can’t two magnetic lines of force intersect each other?
The magnetic field lines never intersect each other because if two or more lines intersect each other than it means that at that point of intersection, the magnetic field has two directions at the same point. This is not possible for a magnetic field to point in more than one direction at the same point.
What is the property of line of force?
1) The electric lines of force start from a positive charge and ends on a negative charge. 2) The electric lines of force always enter or leave the charged surface normally. 3) Electric lines of force can never intersect each other. 4) The electric lines of force cannot pass through a conductor.
What are electric line of force give their important properties?
An electric line of force is a smooth curve drawn in the electric field so that the tangent at any point on the curve gives the direction of electric field at that point. Properties: Lines of force are continuous curves, which start from a positive charge and end on a negative charge.
What are the three properties of electric field lines?
Properties of Electric Field Lines
- The field lines never intersect each other.
- The field lines are perpendicular to the surface of the charge.
- The magnitude of charge and the number of field lines, both are proportional to each other.
Under what condition are the electric lines of force curved not straight?
electric field lines are straight for a uniform electric field. Electric lines of force are straight line when there is single charge. If two electric charges are placed near each othe, the electric lines of force in between them becomes curved slightly.
Why are electric lines of force not closed?
The field lines starts (or diverges) from the positive charge and terminate (or converges) on negative charge. If the electric field lines form closed loop , these line must originate and terminate on the same charge which is not possible because electric field lines always moves from positive to negative.
At what angle electric field lines of force enter and leave the charged surface?
90∘
What are the four properties of electric field lines?
Properties of an Electric Field
- Field lines never intersect each other.
- They are perpendicular to the surface charge.
- The field is strong when the lines are close together, and it is weak when the field lines move apart from each other.
- The number of field lines is directly proportional to the magnitude of the charge.
What are the properties of magnetic field lines?
Magnetic fields can be pictorially represented by magnetic field lines, the properties of which are as follows:
- The field is tangent to the magnetic field line.
- Field strength is proportional to the line density.
- Field lines cannot cross.
- Field lines are continuous loops.
What are the 4 basic properties of the magnetic lines of force?
The magnetic lines of force has the following properties:
- Each line is a closed and continuous curve.
- They originate from the north pole and terminate at the south pole.
- They will never intersect each other.
- They are crowded near the poles where the magnetic field is strong.
