Keep it short & simple. Type complete word. Avoid abusive language.
The net magnetic flux through any closed surface is zero, according to Gauss's Law for magnetism.
Mathematically,
? B · dA = 0.
It states that all magnetic field lines that enter a surface must exit from it as well. In this way, it is different from the electric charges which can exist independently a
The Earth's magnetic field makes a magnetic inclination or dip with the horizontal plane at a particular location. It shows how much the magnetic field is tilted from the horizontal. It gets tilted due to the Earth's magnetic nature. The formula is:
tan I = B_V / B_H,
where B_V is the vertical compon
What is magnetic declination and why is it important?
What is magnetic declination and why is it important?
The angle between the magnetic north (the direction a compass points) and the geographic north (true north) is the magnetic declination. This angle can change over time due to changes in the Earth's magnetic field and varies with location on Earth. It is important for navigation where accurate direc
Can I take admission in Atmiya University BPharm without entrance exam?
As per the Atmiya University admission criteria for BPharm, the selection of candidates is based on the score obtained by the applicants in the last qualifying exam. It is crucial for prospective candidates to meet the requisite eligibility criteria before applying for the desired course. This merit

What is a magnetic dipole and how is its moment calculated?
What is a magnetic dipole and how is its moment calculated?
In a magnetic dipole, two equal and opposite magnetic poles are kept at a small distance. In concept, it is equal to an electric dipole. The magnetic dipole moment (M) represents the strength and orientation of the magnetic dipole and it is a vector quantity. The formula is: M = m * 2l. Here m repre
What is the difference between a magnetic field and magnetic field lines?
What is the difference between a magnetic field and magnetic field lines?
The region around a moving electric charge or a magnetic material where the force of magnetism acts is called the magnetic field. The magnetic field lines are used to represent the strength and direction of the magnetic field and these are imaginary lines. The density of these lines shows the field
Which is the most difficult MDes entrance exam to crack?
While there are many entrance exams conducted for MDes course admission, such as CEED, NIFT Entrance, CUET-PG, etc., among them, NID DAT is considered the toughest. It is a drawing-based paper that tests the creativity and design thinking of a candidate. Also, it is a highly competitive exam with a
