What are the difference between a wire loop and a wire needle?

What is produced when a magnetic field moves relative to a closed wire loop?
Faraday says you will induce a current in the wire.
Why is it necessary to flame the loop between cultures?
because when we inoculate the culture with wire loop,some organism may be sticked to it which may be harmful or can cause trouble.so to destroy the remaining organisms wire loop is flamed again.
What is a loop or cool of wire that can rotate?
AC and DC Dynamo, galvanometers, etc...
For a loop of current carrying wire in a uniform magnetic field the potential energy is a minimum if the magnetic dipole moment of the loop is?
in the same direction as the field
Why flaming the loop when streaking for isolation?
To sterilize it.
Steps in making a smear?
Smear is one of the forms in which organisms are viwed under the light microscope in microbiology, the other form is as wet mounts, remember that smear is used to view killed organisms the steps in making smear are as follow: 1-Get a grease free slide and a wire loop. 2-sterilize the wire loop by flaming. 3-deep the wire loop in a normal saline. 4-touch the slide with the wire loop, there will be a drop of normal saline on the slide. 4-sterilize the wire loop again and touch a small part of a colony in petri dish, then mix it with the normal saline on the slide. 5-allow it to air dry. 6-pass it through an open flame three times(heat fixation). Then view under the microscopes. The heat fixation is done in order to: 1-to fix the smear to the slide. 2-to kill the organism 3-to alter the organism so that it can accept stain readily.

Why if the same current flows in a wire coil and a single wire loop the magnetic field inside the coil is stronger than the field inside the loop?
why, if the same current flows in a wire coil and a single loop, the magnetic field inside the coil stronger than the field inside the loop
A loop of wire is placed within a magnetic field If the loop of wire is stationary as is the magnetic field will a current be induced in the wire?
No it will not. In order to get electrical activity you need motion. Either the magnet or the wire must move.
Why the loop is flamed after completing the inoculation?
because when we inoculate the culture with wire loop,some organism may be sticked to it which may be harmful or can cause trouble.so to destroy the remaining organisms wire loop is flamed again.
What describes the production of an electric current by moving a loop of wire through a magnetic field or moving a magnet through a wire loop?
moving a loop of wire through a magnetic Field. The rotation of a coil of copper wire trough a magnetic field changes magnetic field as "seen" from the coil inducing an alternating current.
Another name for a platinum wire loop?
oese
What is a circuit that only has one loop of wire?
series
Function wire loop?
The function of a wire loop is to transfer small amount of bacterial culture into broth. It is also used to move an agar plate for its continued growth.
When you loop the wire with a current it will?
increase the strenght of the magnetic field. :)
How can a contamined wire loop be cleaned?
insert the loop into the burner flame until all of the salt has been burned off
