A magnetic field around a current carrying wire forms?
concentric circles around the wire
What is the use of concentric circles?
The use of concentric circles is most commonly used on a target. Concentric circles are placed around a target in which each concentric circle has the same center.
What is the observation Oersted Experiment?
when ever a current pass trough a conductor a magnetic field will be produced around that conductor in the for of concentric circles.
He developed the theory that planets move in concentric circles around the earth?
AAristotle developed the theory that planets are spheres and move in concentric circles around the sun
Bone Cells are arranged in concentric circles around the osteonic harversian canals T or F?
True.
Bone cells are arranged in concentric circles around longitudinal tubes called?
osteonic canals
What is the matrix hard owing to calcium salts?
Osseous tissue has cells that are arranged in concentric circles around a nutrient canal matrix and is hard due to calcium salts.
How will you describe the magnetic field around a straight current carrying wire?
Yes, if you place your thumb in the flow direction, the magnetic direction around the wire will be ccw.
Why do Concentric circles arrange around a current carrying conductor only if the cardbord is tapped gently?
The magnetic forces that cause the iron filings to align to the magnetic field are very weak and have trouble overcoming the forces of friction. When you tap the cardboard the filing jump up a bit and while they are in the air they are able to then rotate.
What type of bone has lacunae in concentric circles around central canals and is found on the wall of the middle prtion of the long bone?
Compact bone
What connective tissue is the hardest tissue of your skull cap?
Osseous tissue is the hardest tissue of the skullcap. The cells are arranged in concentric circles around the nutrient canal and the matrix is hard due to the calcium salts.
Why electromagnets work?
When you wrap the wire around the nail, make certain that you wrap the wire all in one direction. You need to do this because the direction of a magnet field depends on the direction of the electric current creating it. The movement of electric charges creates a magnetic field. If you could see the magnetic field around a wire that has electricity flowing through it, it would look like a series of circles around the wire. If an electric current is flowing directly towards you, the magnetic field created by it circles around the wire in a counter-clockwise direction. If the direction of the electric current is reversed, the magnetic field reverses also and circles the wire in a clockwise direction. If you wrap some of the wire around the nail in one direction and some of the wire in the other direction, the magnetic fields from the different sections fight each other and cancel out, reducing the strength of your magnet.How_does_a_electromagnet_work
