Give three properties of bar magnet and magnetic field lines..?

$\Large\underline\mathfrak{Properties of}$

$\rule{200}{4}$

$\Large\bold\star\underline{\underline\textbf{Bar magnet \:}}$

→ A magnet attracts small pieces of magnetic material such as iron, steel, cobalt etc.

→ When a bar magnet is suspended freely, it always points in the north-South direction.

→ Like poles of a magnet repel each other and unlike poles attract each other.

→ Magnetic poles always exist in pairs.

$\Large\bold\star\underline{\underline\textbf{Magnetic Field lines\:}}$

→ Magnetic field lines form continuous closed loops.

→ The tangent to the field line at a given point gives the direction of magnetic field at that point.

→ The strength of magnetic field is determined by the number of magnetic lines of force passing through unit area

» i.e. the larger the number of field lines

crossing unit area, the higher is the value of magnetic field and vice versa.

→ Two magnetic field lines never cross each other.

Answer 2

Answer:

the three properties of bar magnet and magnetic field lines are:-

1)They never intersect each other

2)The tangent drawn from the line is in the direction of magnetic field.

3)They are denser at poles
