What is the main objective of the magnetic field experiment?
What is magnetic lines of force in physics?
Magnetic Lines of Force is a an imaginary line representing the direction of magnetic field such that the tangent at any point is the direction of the field vector at that point.
Where is the magnetic field the strongest?
It is strongest at the poles. So, what are magnetic poles? Magnetic poles are opposite ends of a magnet where the magnetic field is strongest.
What is the scientific term for the strength of a magnetic field?
magnetic field strength, also called magnetic intensity or magnetic field intensity, the part of the magnetic field in a material that arises from an external current and is not intrinsic to the material itself. It is expressed as the vector H and is measured in units of amperes per metre.
How will you describe the magnetic field lines far from the magnet?
If you place a compass near the north pole of a magnet, the north pole of the compass needle will be repelled and point away from the magnet. Thus, the magnetic field lines point away from the north pole of a magnet and toward its south pole.
What is Fleming's left hand rule?
Fleming's left - hand rule states that if we stretch the thumb, middle finger and the index finger of the left hand in such a way that they make an angle of 90 degrees(Perpendicular to each other) and the conductor placed in the magnetic field experiences Magnetic force.
Does a magnets orientation affect its field strength reading experiment?
Does the size of a magnet affect its strength? The short answer is yes, but only because the size of a magnet means that there are proportionally more domains that can align and produce a stronger magnetic field than a smaller piece of the same material.Dec 28, 2020
What magnets attract science project?
Metals such as iron, nickel, and cobalt are attracted to magnets. Steel has iron in it, so it is also attracted to magnets.
What are some methods of creating a magnetic field?
- Method 2 of 3: Making an Electromagnet Gather supplies. Electromagnets are created by running an electric current through a piece of metal to create a magnetic field. Strip the ends of the wire. Use the wire strippers to remove a few centimeters of insulation from either end of the copper wire. Wrap the nail. ... Connect the battery. ... Use the magnet. ...
Does a magnetic field really exist?
- However, purely magnetic fields do exist . Therefore, magnetic fields are more than just relativistic electric fields. The correct statement is that electric fields and magnetic fields are both fundamental, both are real, and both are part of one unified entity: the electromagnetic field.

What is the evidence that a magnetic field exists?
- The earth has a magnetic field pointing almost north-south—only 11.5° off. This is an excellent design feature of our planet: it enables navigation by compasses , and it also shields us from dangerous charged particles from the sun. It is also powerful evidence that the earth must be as young as the Bible teaches.

What is an example of a field experiment?
- Examples include: Clinical trials of pharmaceuticals are one example of field experiments. Economists have used field experiments to analyze discrimination, health care programs, charitable fundraising, education, information aggregation in markets, and microfinance programs.
