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.

Faraday says you will induce a current in the wire.
FR --> Fire Retardant FRLS-->Fire Retardant low smoke When ever wire gets fire Fr wire emit more smoke where as FRLS wire emits low smoke than the FR wires...
AC and DC Dynamo, galvanometers, etc...
it point same way as magnetic field
it point same way as magnetic field
You will have flamed the inoculating loop or needle long enough when the entire wire or metal is glowing red-hot. This sterilizes the tool, ensuring that no contaminants are introduced into your sample.
The shape of the loop of wire is two concentric semicircles.
The potential difference between the terminals of a connection wire is determined by the voltage difference applied across the wire. This voltage difference creates an electric field within the wire that causes charge carriers to move and establish a potential difference between the terminals.
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.
Its tip is a wire made of platinum or nichrome, the latter being inferior but less expensive. The wire forms a small loop with a diameter of about 5 mm. This loop is handy for taking an inoculum from a liquid by using the phenomenon of surface tension. The loop is used to cultivate microbes in Agar jelly and to use the streak manouvre to transfer microbes.
To provide conversion between the four-wire handset and the two-wire local loop
An important type of winding wire
Usually piercing needles are hollow to allow for the easy insertion of the jewelry so no wire is needed.
The magnetic needle gets deflected near a current-carrying wire due to the magnetic field generated by the current. The magnetic field induces a force on the needle, causing it to align or deflect towards or away from the wire. This phenomenon is a result of the interaction between the magnetic field and the magnetic properties of the needle.
Yes, the red wire is a positive wire (+) and the black wire is a negative wire (-) :D
