Magnetic field around a magnet is represented by magnetic field lines forming closed loops. Explain.

Content Curator

The magnetic field around a magnet is represented by magnetic field lines that form closed loops. This means that the magnetic field lines originate from one pole of the magnet, extend outwards, and eventually return to the opposite pole. The following points explain this concept in more detail:

Magnetic Monopoles: Unlike electric charges, magnetic charges (called magnetic monopoles) do not exist in nature. This means that magnetic field lines always form closed loops since they must start and end on opposite poles of a magnet.
North and South Poles: A magnet has two poles, north and south, and the magnetic field lines originate from the north pole and end at the south pole. The direction of the magnetic field lines is from north to south.
Magnetic Field Strength: The strength of the magnetic field is proportional to the number of magnetic field lines passing through a given area. The density of the magnetic field lines represents the strength of the magnetic field in that region.
Magnetic Field Shape: The shape of the magnetic field around a magnet depends on the size, shape, and orientation of the magnet. For example, the magnetic field lines of a bar magnet extend from the north pole to the south pole and form a loop around the magnet.
Magnetic Field Interactions: When two magnets are brought near each other, the magnetic field lines interact with each other. If the poles of the two magnets are the same, the magnetic field lines repel each other, while opposite poles attract each other.

In summary, the magnetic field around a magnet is represented by magnetic field lines forming closed loops due to the absence of magnetic monopoles, with the magnetic field strength being proportional to the number of magnetic field lines and their density. The shape and orientation of the magnetic field around a magnet depending on the size, shape, and orientation of the magnet. When two magnets are brought near each other, the magnetic field lines interact with each other based on their polarity.

A charged particle $+q$ in an electric field $\vec{E}$ experiences a force in the direction of the electric field. As a result, its kinetic energy changes. Similarly, the charged particle also experiences a force when it moves in a magnetic field $\vec{B}$. But this magnetic force is perpendicular to both velocity $\vec{v}$ of the charged particle and the magnetic field $\vec{B}$, so it cannot change the kinetic energy of the charged particle. Consider two charged particles 1 and 2 of masses $m$ and $\frac{m}{2}$ having charges $-q$ and $+2q$ respectively. They are accelerated from rest through the same potential difference $V$ and acquire kinetic energy $K_1$ and $K_2$. Then they enter in a region of uniform magnetic field $\vec{B}$ perpendicular to their velocities.
