How can prevent splattering when flaming a loop which has just used to transfer a culture?
you should drawn the loop slowly from the cooler to the hotter part of flame.Heat from the base of the wire first and slowly move towards the loop's tip. Heat the wire until it is red-hot.
When a magnet is pushed through a loop of wire what does it produces?
When the magnetic flux (field) intersecting a loop of wire changes, a voltage is induced between the ends of the loop. If a resistor is connected between the ends, a current flows and power is produced, but in this case a force is needed to move the magnet, and this provides the power.
Why is an wire loop heated in a Bunsen burner?
For sterilization purposes. The process of heating the loop to white hot kills all bacteria that remain between samples.
In which direction should you move the inoculating loop in the Bunsen burner flam?
When sterilizing a loop, grasp the handle firmly and begin flaming it starting at the end near the grip, flaming slowly down towards the loop, being sure that the wire is glowing orange. This ensures that the loop is being flamed properly and sterilizing.
Why are the live wire and neutral wire never joined together?
An electrical circuit forms a loop. The "live" or hot wire supplies the voltage, which is returned on the neutral. If the hot wire and neutral wire were connected together without a load between them, the circuit would be short out and trip the circuit's protection device.
What are the difference between a wire loop and a wire needle?

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.
Why is it required a clean wire loop in order to observe a spectrum?
Classic Wire Loop MethodFirst, you need a clean wire loop. Platinum or nickel-chromium loops are most common. They may be cleaned by dipping in hydrochloric or nitric acid, followed by rinsing with distilled or deionized water. Test the cleanliness of the loop by inserting it into a gas flame. If a burst of color is produced, the loop is not sufficiently clean. The loop must be cleaned between tests.The clean loop is dipped in either a powder or solution of an ionic (metal) salt. The loop with sample is placed in the clear or blue part of the flame and the resulting color is observed.Wooden Splint or Cotton Swab MethodWooden splints or cotton swabs offer an inexpensive alternative to wire loops. To use wooden splints, soak them overnight in distilled water. Pour out the water and rinse the splints with clean water, being careful to avoid contaminating the water with sodium (as from sweat on your hands). Take a damp splint or cotton swab that has been moistened in water, dip it in the sample to be tested, and wave the splint or swab through the flame. Do not hold the sample in the flame as this would cause the splint or swab to ignite. Use a new splint or swab for each test.
When you loop the wire with a current it will?
increase the strenght of the magnetic field. :)

Why is the magnetic field strngth inside a current carrying loop of wire greater than a strraight section?
A looped wire would have a stronger magnetic field because a looped wire is closer to the magnet all the way aroud.
