Magnetic Abrasive Finishing of Thick Cylinder Tube

Abstract Magnetic Abrasive Finishing (MAF) is an advanced finishing method, which improves the quality of surfaces and performance of the products. Surface is finished by removing the material in the form of microchips by abrasive particles in the presence of magnetic field. The material is removed in such a way that surface finishing and deburring…

Immobilization of Amylase on Magnetic Nanoparticles

Abstract α-amylase was immobilized covalently on iron oxide magnetic nanoparticles. The synthesis of magnetic nanoparticles was done by the coprecipitation conventional method. The chemical composition and particle size of the synthesized particles was confirmed via X-ray diffraction. Tyrosine, Lucien and chitosan and glutaraldehyde were investigated to make a covalent binding between the iron oxide magnetic…

Magnetic Separator Should Note the Following Points

The magnetic separator is one of commonly used preparation equipments in magnetic separation factory. It has dry and wet two types. According to types of magnets, it can be divided into permanent magnet type and electromagnet type. It is also can be divided into strong magnet type, middle magnet type and weak magnet type according…

The higher the resistance

Aim – To see if the length of wire will affect the resistance Factors – I will be changing the length of the wire Prediction – I predict that the longer the wire the higher the resistance Fair test – To make my experiment a fair test I will: iKeep the voltage and amps the…

Find out if speed affects stopping distances

Trolley Experiment By Chris Mayhew Trolley Experiment Planning Aim: We are trying to find out if speed affects stopping distances What I already know: The equation for speed is: Velocity (speed) = displacement (distance) Measured with a ruler Time Measured with a ticker timer Pilot experiment (simulation): Method: 1. First load up the program ‘Science…

Investigation of resistivity of nichrome wire

32 Gauge 28 Gauge Voltage Recorded Percentage Uncertainty % Ammeter The ammeter recorded the current of the circuit with the wire connected to it. 32 Gauge 28 Gauge Current Recorded Percentage Uncertainty %(??? Current Recorded Percentage Uncertainty. Resistance Thus, as the resistance is calculated using the voltage and current obtained, we have the following resistance…

The wire showing its resistance

I want to find out how the length of a wire changes the amount of voltage and current flowing though the wire showing its resistance. My prediction for the experiment is that as the length of the wire increases the resistance will also increase and as the wire decreases so will the resistance. I think…

Mains electricity

When people first started looking carefully at what electricity was they decided it was something to do with particles carrying charge in a wire. They decided that they thought positive particles started at the positive side of a circuit and worked their way around until they reached the negative side of the circuit. This idea…

The most energy

Make sure it’s on the same flame all the time.  Make sure its the same amount of water all the time (20cm )  Make sure the Bunsen burner isn’t too close to the test tube. Stir the water before taking the temperature.  Always weigh the crisp each time. RISK MINIMISING RISK Burning bench Use bench…

Resistance of a wire coursework

Then we measured the first measurement of resistance at 100a?? c, increasing the temperature too over 300a?? c. Taking s measurement at every 10a?? c. At one point in the investigation the heat started to melt the plastic coating around the wires, we quickly noticed this was a problem so we attached the wire to…
