Biot-Savart’s Law Experiment
OBJECTIVES
- Measuring the magnetic field of a straight conductor and of circular conductor loops as a function of the current.
- Measuring the magnetic field of a straight conductor as a function of the distance from the axis of the conductor.
- Measuring the magnetic field of circular conductor loops as a function of the loop radius and the distance from the loop.
PRINCIPLE
Electric currents generate magnetic fields. Biot–Savart law is an equation describing the magnetic field generated by a constant electric current. It relates the magnetic field to the magnitude, direction, length, and proximity of the electric current. In this experiment, we study the magnetic field characteristics in the straight conductors and different types of circular coils.BSL1-C -

Pin Diode Characteristics Experiment
OBJECTIVES
- To study the response of PIN diode, in the following conditions:
- Photocurrent (Iph) vs Applied voltage at constant irradiance (Φ) under Reverse biased condition of the PIN diode.
- Current (I) vs Voltage (V) under forward bias condition of the PIN diode.
PRINCIPLE
The PN-Junction diodes, though versatile, have a few limitations regarding the amount of current they could handle before breakdown and also have low switching frequency, low power handling capacity, and low quantum efficiency. To overcome all these issues PIN diode was designed. PIN diodes are also extensively used as photo diodes in PIN photodiode configuration and are very important in optical fiber communication.

BH Curve Experiment
Objectives
To observe and study the magnetization behaviour of the ferromagnetic magnetic materials provided.
Principle
The B-H curve is the curve characteristic of the magnetic properties of a material or element or alloy. It tells you how the material responds to an external magnetic field, and is a critical piece of information when designing magnetic circuits. A Ferromagnetic material, retains its magnetization even after the external magnetic field is removed. And the reversal or change in the direction of the applied external magnetic field results in a change in the magnetization of the ferromagnetic material. It is seen that the change in the magnetization lags behind the change in the applied external magnetic field. Thereby, a hysteresis behaviour is exhibited.
Key Features
- Compact Setup –  The apparatus design is compact and yet effective to perform the experiments with ease. The simple connections and stand to hold the teslameter probe, makes it easy to handle.
- Multiple samples included – Multiple ferromagnetic samples are provided to study the BH curves of the different materials. The removable cores make it easy to change between samples.

Millikan Oil Drop Apparatus
Supertek’s Millikan Oil Drop Apparatus is a contemporary version of the classic design which allows the students to observe the velocity of an oil drop rising and falling in an electric filed. The apparatus is equipped with camera which allows the user to connect it with the computer screen for an easy viewing of the droplets. It permits the calculation of the force acting on the charge carried by the oil drop.

Interferometer Experiment
Objectives
- To produce and observe the interference pattern.
- To measure the wavelength of laser source using the interferometer.
Principle
Phenomena of interference can be explained by the principle of superposition. Consider two E.M waves simultaneously propagating through the same region of space. The resultant electric field at any point in that region of space is the vector sum of the electric field of each wave. Depending on the strength of the resulting electric field at a point in space where the two waves superpose, we observe dark and bright regions in the interference pattern.
Key Features
- Easy to Setup – The apparatus is built on a sturdy and portable platform. The legs are height adjustable to aid leveling of the platform & precise optical alignment of the laser beam. All this reduces the time taken for setup and aids the ease of measurements.
- High quality beam splitter and reflective mirrors – The setup comes with 40 x 40 x 40mm beam splitter cube and 40 x 40mm (98% highly reflective) mirrors for clear fringe pattern.
- 1 micron step movement – The complex double lever mechanism enables a least count of 1 micron in movement of the fixed mirror. Measurement error is less than 5% in wavelength measurement.
