Magnetic Field
Q1: Define Magnetic Field.
Answer:
A magnetic field is a region around a magnet or a moving charged particle that exerts a force on other magnets or moving charges.
Q2: What causes Magnetic Field?
Answer:
A magnetic field is caused by the motion of charged particles, such as electrons, in a magnetic field.
Q3: What is the Unit of Magnetic Field?
Answer:
The unit of magnetic field is the tesla (T) in the SI system and in CGS system unit of magnetic field is Gauss(G).
Q4: What is the Difference between a Magnetic Field and an Electric Field?
Answer:
The key difference between both a magnetic field and an electric field is that a magnetic field is produced by the motion of charged particles, while an electric field is produced by the presence of an electric charge.
Q5: How do Magnetic Fields affect Materials?
Answer:
Magnetic fields can cause certain materials, such as iron, to become magnetized, which can then exert magnetic forces on other materials.
Q6: Can Magnetic Fields be harmful to humans?
Answer:
Highly intense magnetic fields can be harmful to humans, causing headaches, dizziness, and other health problems. However, the magnetic fields encountered in everyday life are generally not strong enough to cause harm.
Q7: Define Magnetic Field Lines.
Answer:
Magnetic field lines are the imaginary lines around the source of the magnet which can be used to represent the direction of the magnetic field at that point.
Q8: Why do Magnetic Field Lines never Intersect?
Answer:
Since magnetic field is a vector field, the lines denote the direction of magnetic field. If two magnetic field lines intersect each other, there will be two directions of the magnetic field at a single point which is not possible. Thus, magnetic field lines do not intersect each other.
Q9: What is Magnetic Field Intensity?
Answer:
The measure of strength of the magnetic field is called magnetic field intensity and it is denoted by H.
Q10: By Which Instrument the Presence of a Magnetic Field can be determined?
Answer:
A magnetometer is the device used to measure the magnetic field in an area, magnetic needles can also determine direction and presence of magnetic field.
Magnetic Field
Magnetic Fields is the region around a magnet in which it exerts a force on other magnetic material. The magnetic field of the earth protects us from harmful solar radiation as well as the production of electricity for homes is also an application of the Magnetic Field. Thus everybody should know about the basics of it. In this article, we will explore the concepts of magnetic fields in a well-detailed manner. Other than that we will also learn about the magnetic field line, its properties, application, and intensity as well. So, let’s explore the fascinating world of magnetic fields and learn how they shape our lives.
